RE: [ft-devel] About the Cmap format 12

[丁力]

I have not use the debug of the freetype. I use the tools "TrueType v1.0 Dump 
Program" which is download from Microsoft websit.
And I see the cmap table in the dump result. 

For example, if I want get the character "壬", and the "壬"'s Unicode is 58EC.
In the font the "壬"'s index is 4766:
                      Char 0002123A -> Index 4764
                      Char 0002123B -> Index 4765
                      Char 0002123C -> Index 4766------------------this is the 
character "壬"
                      Char 0002123D -> Index 4767
                      Char 0002123E -> Index 4768

And I got the table information is:
Subtable  3.   Platform ID:   3
               Specific ID:   10
               'cmap' Offset: 0x00000142
              ->Format: 12 : Segmented coverage (32 bit)
                Length:         40
                Version:        0
                Seg   1 : startCharCode = 00000020, endCharCode = 0000007F, 
startGlyphCode = 2
                Seg   2 : startCharCode = 00020000, endCharCode = 0002A6D6, 
startGlyphCode = 98

I have see the code which parse the format 12, I don't think it can deal with 
this cmap table. 
So in my project it always get glyph index 0.

How do you think using FT2_DEBUG if Ding Li kindly accepts recompile 
FT2 with defining FT_DEBUG_LEVEL_TRACE?

You can compare debug output of yours and Ding Li's.
