Font selection problem in Lilypond

[Didi Kanjahn]

> I'm not top posting
Sometimes Lilypond does not select the correct font. It seems to have to do
either with the length of the font name or the number of spaces in the font 
name.
The lines 3 and 4 should be rendered in 2 different fonts so that line 3 is
essentially identical to line 2 (It is because of this problem that I changed
the font name).
However, it seems that Lilypond is defaulting to the font 'Khmer Mondulkiri' for
line 3 where the selected font name is 'Khmer Mondulkiri book'.

The font names are: 
Line 1:  Khmer OS
Line 2:  Khmer Busra
Line 3:  Khmer Mondulkiri book
Line 4:  Khmer Mondulkiri

The problem is old and was recently reproduced using Lilipond versions 2.13.3
and 2.13.19.

The file 'test (MS Word).pdf' shows the correct rendering of the lines, created
in MS Word on the same computer on which 'test Khmer Unicode 2-13-3.pdf' was
produced.

All fonts can be made available - they might be too big to attach here.
All of the above was done under Windows XP.

The font 'Khmer OS' can be downloaded at:
