If a React-generated PDF shows missing, garbled, or substituted characters, register a TrueType (TTF) font that contains those characters before writing text. jsPDF’s 14 standard PDF fonts are limited to the ASCII code page; UTF-8 text that needs other glyphs requires a custom font. The essential order is: load the font data, add it to jsPDF’s virtual file system, register its family and style, select it, then call text().
Why fonts go missing in a jsPDF export
A browser font applied with CSS does not automatically become a font embedded in a PDF. jsPDF writes PDF text using the font selected in the jsPDF document. Its 14 standard PDF fonts are limited to the ASCII code page, so characters outside that coverage—such as accented letters, many currency symbols, or characters from other writing systems—may fail unless you use a custom font containing the required glyphs. The jsPDF documentation advises integrating a custom font for UTF-8 and checking that it supports the wanted glyphs: jsPDF guidance on Unicode characters.
There are two separate things to verify: whether jsPDF has the font available and selected, and whether the font contains each character you need. Successful registration cannot supply a glyph that is absent from the font.
Reproduce the problem with the exact text
- Make a minimal export. Include the exact text that fails, preserving punctuation, accents, symbols, and language characters. This helps distinguish a coverage issue from a layout or styling issue.
- Identify the failing characters. If ASCII text works but non-ASCII text does not, test first with a custom font rather than changing React or CSS font styling.
- Check the chosen TTF’s coverage. Confirm that it includes the actual characters and the style or weight you intend to use. A font family name alone does not guarantee coverage.
- Confirm registration happens before text output. The font bytes must be available, its file registered with the intended family and style, and that family selected before
doc.text().
Choose how to provide the TTF font
The jsPDF project documents two integration routes: generate a JavaScript module with its font converter, or load the TTF data at runtime and register it directly. The right choice depends on how your React build handles assets and when the font is needed; the project does not publish a performance comparison between the approaches.

| Route | Where font data lives | Best fit | Check |
|---|---|---|---|
| Converter-generated JavaScript module | Embedded as base64 font data in generated JavaScript, with registration code | The font is bundled with the application and reused in exports | Ensure the generated module is imported into the code path that creates the PDF |
| Runtime TTF loading | Loaded as TTF content and passed to jsPDF during the export flow | Your app already loads the asset dynamically or needs to control when it is fetched | Wait for loading to finish before creating text; handle a failed font request |
Converter-generated module
The project’s font converter accepts a TTF and produces a JavaScript file containing base64 font data and jsPDF registration code. This puts the font content into an application module. Import and run that module on the path that produces the document; do not assume that placing the file somewhere in the project makes it part of the bundle. The converter implementation registers an addFonts event that adds the font file to the virtual file system and registers its family and style. See the jsPDF font converter.
Runtime TTF loading
Alternatively, load the font content and call addFileToVFS() and addFont() yourself. Loading may be asynchronous in a React application, so make the export function wait until the TTF data is ready. The example below shows the required registration sequence after a binary string is available.
Register and use a custom font in React
Install jsPDF in your app if it is not already installed, then import it in the module that creates the export. The project README shows the standard React-style import, import { jsPDF } from "jspdf", and describes importing jsPDF like another third-party library: jsPDF README.

Once you have the TTF’s contents as a binary string, register the file and select the same family and style before writing text:

export function exportPdf(fontBinaryString) {
const doc = new jsPDF();
// Add the TTF contents to jsPDF's virtual file system.
doc.addFileToVFS("MyFont.ttf", fontBinaryString);
// Register the filename under a family name and style.
doc.addFont("MyFont.ttf", "MyFont", "normal");
// Select that exact family before writing text.
doc.setFont("MyFont", "normal");
doc.text("Text with the required glyphs: café, €, 漢字", 10, 10);
doc.save("export.pdf");
}Replace the sample text with representative content from your application. The key is not the literal names MyFont.ttf or MyFont; the filename passed to addFont() must match the file added to the virtual file system, and the family/style passed to setFont() must match a registered font. The font data must be a binary string in the format expected by this workflow—not an unresolved asset URL.
Load the font before calling the export function
If your app retrieves the TTF asynchronously, resolve that load before constructing and writing the document. A minimal flow using a request for a font file is:

async function loadFontBinaryString(fontUrl) {
const response = await fetch(fontUrl);
if (!response.ok) {
throw new Error(`Font request failed: ${response.status}`);
}
const buffer = await response.arrayBuffer();
const bytes = new Uint8Array(buffer);
let binary = "";
for (const byte of bytes) binary += String.fromCharCode(byte);
return binary;
}
async function exportWithLoadedFont() {
const font = await loadFontBinaryString("/fonts/my-font.ttf");
exportPdf(font);
}This illustrates the ordering requirement; make sure the URL and asset-handling approach suit your bundler and deployment. If the request fails, do not continue with an empty font string: surface the error and prevent a misleading export. For large fonts, avoid repeatedly loading and converting the same file for every export; keep a successfully loaded font available for reuse where that fits your app’s lifecycle.
Use distinct registrations for distinct styles
If your PDF needs bold or italic text, register the corresponding font file and style as well, then select the appropriate registered style. Do not assume that selecting bold will create the bold glyph design from a normal-only TTF. Confirm the available style files and register them under the family and style names your code will select. Likewise, choose a font based on the glyphs needed across all exported text, not just the first failing word.

Test the export and the deployed React build
- Export a small PDF containing the exact characters that previously failed.
- Verify plain ASCII text too, so you can tell whether the font change introduced a broader regression.
- Test every language, symbol, and style your app actually emits. A successful sample does not prove coverage for characters it does not contain.
- Run the export through the production build and deployment path. Confirm the generated font module or TTF asset is included and reachable there.
- Open the resulting PDF in the viewer used by your users. If only one viewer appears wrong, compare the same file in another viewer before deciding the issue is font registration; viewer-specific behavior is not established by the jsPDF guidance cited here.
Check the font’s licensing and redistribution terms before bundling or serving it. The fact that a TTF can be technically registered does not itself grant permission to embed or redistribute it.

Troubleshoot common React and jsPDF font failures
| Symptom | Likely check | Fix |
|---|---|---|
setFont() runs, but text is still wrong |
Compare the family and style in setFont() with those registered by addFont(); verify the font module or data has loaded before export. |
Use matching names and enforce the sequence: load, add to VFS, register, select, write. |
| Some characters print and others disappear or look garbled | The TTF may lack the particular glyphs in the failing text. | Choose and test a font that covers those exact characters; registration does not add missing glyphs. |
| It works in development but not in the built app | The generated font module may not be imported on the export path, or the bundler may not resolve the asset as expected. | Inspect the production bundle and asset request, then use the asset-import method supported by your React bundler. The jsPDF project does not provide a complete recipe for every framework or bundler. |
| The font request fails or export races the request | The export may run before asynchronous loading finishes, or the deployed font URL may be wrong. | Await the load, check the response status, and report a useful error instead of exporting with missing font data. |
| TypeScript says a method is unavailable | The installed jsPDF version and available declarations may differ. | Check the package version and its type declarations against the methods used. The project says it provides TypeScript typings, but that does not establish compatibility for every release or plugin declaration. |
| The PDF looks wrong in only one viewer | The viewer may be an environment variable; the cited project material does not establish a viewer-specific cause or workaround. | Compare the same exported file in another viewer, and verify registration and glyph coverage before changing code for a single viewer. |
React configuration is separate from font registration
The jsPDF README discusses importing the library into React and notes that Create React App users configuring externals can use react-app-rewired or eject for external configuration. That note is about external configuration, not a required step for adding a TTF font. Do not eject or change bundler configuration solely because glyphs are missing unless you have separately identified an asset or module resolution problem. The README does not provide a universal font-asset recipe for all React frameworks, so verify the details against the framework and jsPDF version in your project.
