Could you compare against _both_ the real checksum and
Yes, I should file the bug with yet another sample
with free fonts (NEC FA-xxx fonts are proprietary)
including the clarification you commented.

The problem are subsetted fonts, I believe.

One of the possibility (workaround for OOo) is the
extension of the tricky font detection by the name.
At present, only family name is compared, additional
checking PostScript name may be helpful for this issue.
OOo retains the name table (which is optional in
Type42 spec), so MingLiU can be
Ah, Bevan's proposal is reasonable...
I selected 3 Type42-required subtables (cvt/fpgm/prep)
which are very difficult to subset without detailed
interpretation of glyf program. So, even if the embedded
fonts are subsetted, usually they are same with original
fonts.
# If they are modified, it
Just I've uploaded an archive:
http://gyvern.ipc.hiroshima-u.ac.jp/~mpsuzuki/ooo-ttf-checksum-test.zip
it includes following files:
* LiberationSerif-Regular.ttf - a free font including cvt/fpgm/prep tables
* LiberationSerif.odt - an ODT document referring LiberationSerif font
*
Considering that the number of blacklist is increased to 13, I
changed the algorithm to compare the checksums slightly.
It seems that the fonts are not so popular, so this is not urgent
issue. Please give me comment.
Your patch looks fine. I haven't tested actually whether it works,
but i
