I'm not convinced that this is a bug in these fonts, although it is possible to
work around it by changing them.

Lmaru and lcedar contain Format 0 and Format 4 cmap subtables. The format 0
subtable is for Mac byte mappings, and the Format 4 is for Windows Unicode BMP
mappings.

Examining the Format 4 subtable shows that there are only 11 glyphs mapped
between U+0080 and U+00FF. However, gucharmap shows many more Lmaru glyphs
here.

I suspect that gaps in this area are being filled in incorrectly by also using
the Format 0 subtable.

Removing the cmap format 0 subtable corrects this problem, and all available
Lmaru glyphs are shown in their proper locations, as far as I've been able to
judge.

Unfortunately, I have only managed to construct the font with work-around on
RHEL5, as fonttools/ttx on Fedora has a bug which prevents Lmaru being rebuilt
from a TTX file (bug #688713). (My apologies Akira; I've been trying to solve
that one before filing the bugs you asked me to file on these fonts.)

So, I think that the _real_ bug is present in whichever component of the font
stack uses both subtables to place random glyphs at odd encodings, but I don't
know where to assign that one.

Right. this simply works for a workaround though, I guess the real issue should
be in freetype as the rendering library.

There seems the apple roman support code in fontconfig and getting rid of those
code fixes this issue.
