There is a misconception of how TTCs work: As soon as you select a face index, you can't distinguish the data from a TTF. In other words, it is not possible to specify where a glyph comes from. Most TTCs share a single `glyf' table for all subfonts. However, some fonts (most notably on the Mac) have more than a single `glyf' table. Assuming that font 1 in the TTC accesses `glyf' table 1, and font 2 accesses `glyf' table 2, there is no possibility that you can get glyphs from `glyf' table 2 while accessing font 1. > At the moment FT_Get_Char_Index is returning 0 for the CJK Ideograph > at U+7380, and the error symbol is being used.

Try the ftview demo program without command line option `-e'; the font faces in the TTC are then accessed by glyph indices instead of character codes, bypassing the cmap table. > Any insight into TTC font files or this specific issue would be > appreciated. I strongly suggest that you read TTC section in the TrueType specification: http://www.microsoft.com/typography/otspec/otff.htm Werner _______________________________________________ Freetype mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/freetype
