+gofpdf supports UTF-8 TrueType fonts and “right-to-left” languages. Note
+that Chinese, Japanese, and Korean characters may not be included in
+many general purpose fonts. For these languages, a specialized font (for
+example, NotoSansSC for simplified Chinese) can be used.
 
 Also, support is provided to automatically translate UTF-8 runes to code
 page encodings for languages that have fewer than 256 glyphs.
