Keiji Suzuki commented on PDFBOX-2524:
--------------------------------------
John, those two are about embedded Type0/CIDFontType2 CJK fonts without
subsetting.
My original patches include TTF subsetting and Type0/CIDFontType0 CJK fonts.
About TTF subsetting, I will send a new patch to PDFBOX-2565 but where will I
send a patch for Type0/CIDFontType0 CJK fonts? Are you going to create another
ticket for it?

> I made two PDFont classes for creating PDF documents in CJK and
> non-ISO-8859-1 languages.
> One is PDType0CJKFont. This is for using CJK fonts included in the Asian font
> package of Adobe Reader. This font doesn't require the target font at the
> time of creating PDF documentary. This font uses UTF-16 as a text code and
> supports surrogate pair characters.
> The other is PDType0UnicodeFont. This is for using TrueType Type0 Font which
> can deal with any Unicode characters like a ArialUnicodeMS. Only the
> characters which are used actually in the document are embedde. Realizing
> this, you have to call the PDType0Unicode.reloadFont() method just before
> closing PDPageContentStream. I think this specification is ugly, but I could
> not thought of a suitable way to remove this spec. This font uses the
> original glyph code of the embedded font as a text code and supports
> surrogate pair characters too.
> Example programs using these two fonts are also attached.
