[Fonts] Combining characters

[Anuradha Ratnaweera]

Let me put this in a simple point form using a hypothetical example:

- I have a font (non-unicode) X, which has non latin characters in the range of 32 to 127.
- The same character set is defined in Unicode 3/4 from say 4000.
- Unicode characters 4001 and 4010 form a single composite character which is the same as character 51 in the font X
- There is no Unicode equivalent to the 4001+4010 combination

Now, if I want to render character 51 of X inplace of the composite character 4001+4010, how should I proceed? Is there a way to map unicode sequences to actual (physical) fonts. Prefarably in the form:

4001,4010 - X,51

  Your problem is not new and has been worked on for many years
by a number of people and today we have a few satisfactory solutions.

  You crossposted to a few lists I subscribed to. Although
I've already answered to you on gtk-i18n list, here I'm gonna
give you some URLs:
