Description

I can't find a way to use Japanese font with jsPDF.

I've created the font with the fontconverter using Noto Sans JP from Google Font, I've imported it but I can't use any Glyphs that I find on the Google Font page here: https://fonts.google.com/specimen/Noto+Sans+JP#glyphs

I can see that the font is imported because it changes if I remove the font script.

Here is a CodeSandbox that reproduces the error: https://codesandbox.io/s/busy-joliot-jwjy8?file=/main.js

I also tried with others fonts, without any better results.

I am using jsPDF in a web application with users from all around the world and I am gettings requests from Japanese to handle it. Any help would be very appreciated!

Thanks

Direção de pesquisa
Investigate the font embedding mechanism in jsPDF, particularly how glyphs are encoded for CJK fonts. The user provided a CodeSandbox (https://codesandbox.io/s/busy joliot jwjy8) that reproduces the issue. Check existing issues or PRs related to Japanese font support. The problem may be in the addFileToVFS or addFont methods, or in the default encoding not supporting Japanese characters. Look at the fontconverter output format and compare with supported formats.
