[xep-support] Mixing Chinese and English fonts

[Alexander Peshkov]

Hello Bob,

It seems to me that the natural way to solve your problem is to place
English font before Chinese font in the fonts list and specify
'character-by-character' font selection strategy:
  <fo:block font-family="EnglishFont, ChineseFont" font-selection-strategy="character-by-character">

In this case formatter will use EnglishFont for all Latin characters
and switch to ChineseFont for all Chinese characters. The only
possible drawback is that all common characters (such as punctuation
symbols) will be taken from EnglishFont also (don't know whatever it's
acceptable in your case or not).
As for for font modification - if you use Type 1 font you can simply
remove undesired glyphs records from .afm file in order to make
appropriate glyphs unavailable.

Best regards,

BS> I have XML documents that are primarily Chinese but with occasional English

BS> We would like to substitute a better font for the English characters.

BS> I understand that with XSL-FO 1.0 you can provide a comma-separated list of

BS> I would like to avoid having to put all the English words within fo:inlines
BS> to switch fonts. So we are considering using something like Fontographer to
BS> edit the (open source) Chinese font to remove the Latin characters.  I
BS> believe this will then force XEP to switch to the secondary font-family when
BS> a Latin character is encountered in the input.  Is this a sound strategy?
BS> Has anyone attempted this?
