On MacOS X, it seems that the symbols for x:maj7 and x:m7.5- still don't work properly in 2.5.19 (The former is omitted, the latter printed as a long box). Is this a known bug or is it a platform specific problem?
This is font related problem. Lily uses Unicode codepoints, and lets
pango decide which symbol to use. At the moment, Greek Capital Delta is
used for the white triangle, from chord-modifier-init.ly:
whiteTriangleMarkup = \markup { %% 394 capital delta #(ly:export (ly:wide-char->utf-8 #x0394))
%% 2206 : delta from the symbol font. % #(ly:export (ly:wide-char->utf-8 #x2206))
%% up pointing triangle % #(ly:export (ly:wide-char->utf-8 #x25B3))
None of these variants show up, and neither does the #x00F8 for the .m7.5-, although all of these characters are supported in dozens of fonts.
Pango should select a font that contains these glyphs.
I'm afraid I'm not all that familiar with pango. Are there any debug environment variables that I could set to trace pango, or any suggestions what API call I should intercept to see when it's looking for these characters.
Can you verify that the standard Mac fonts do not cover these codepoints?
They do.
I see two options: - draw a triangle by hand (robust)
But probably not very extensible to other font styles.
- making sure that a font with appropriate glyphs is installed.
It would seem to me that that should be the proper resolution.
