[ft-devel] RE: Can not read the glyph~

[丁力]

En。。。。。。

Can you tell me which files you have change? I need a stable vision, I want 
merge you code to vision 2.3.7.

Because my internet connection has some problems, I have not test yet. I will 
test it as soon as possible.

Thanks.

Hmm.

The font is broken.  The `loca' table says from itself that it has a
length of 58254 bytes.  Since the loca format is 1 (given in the
`head' table), 4 bytes are used per entry.  This gives 14563 entries.
However, the `maxp' table says that there are 29126 glyphs in the
font.

BTW, the table directory of this font is broken too: The specification
says that the entries have to be sorted by tag.  However, this is not
the case:

  glyf  -  00038f60  -  00011bfe
  loca  -  0001c840  -  0000e38e
  head  -  000000a0  -  00000036
  maxp  -  00000100  -  00000020
  hhea  -  000000d8  -  00000024
  hmtx  -  00000124  -  0001c718
  prep  -  0004ab60  -  000002a4
  cvt   -  0004ae08  -  000002a0
  fpgm  -  0004b0ac  -  00000950

[This is harmless, but...]

However, I've made this font work with the current CVS.  Please test.
