I have been looking at version 2.12.2 (as installed by the Ubuntu
package) and this too has font problems. I am beginning to think the
problem only effects lilypond on Ubuntu.

1] Doing:

        $ lilypond -dno-delete-intermediate-files myfile.ly
        
        where myfile.ly is:
        
        { \times 3/4 c' }
        
        with either 2.12.2 or 2.13.12.The PDF doesn't look correct. The
        header of the ps file shows the following fonts are loaded:
        
        %%DocumentSuppliedResources: font CenturySchL-Roma
        %%DocumentSuppliedResources: font CharisSIL
        %%DocumentSuppliedResources: font Emmentaler-20

2] Something has changed since 2.12.2 since:

        $ lilypond -dbackend=svg myfile.ly
        
        does produce a readable svg file (but with the wrong font, of
        course) with version 2.12.2. However, with version 2.13.12 it
        produces an unreadable svg file and the error:
                
        Layout output to 
`myfile.svg'.../home/consultant/lilynew/lilypond/out/share/lilypond/current/scm/lily-library.scm:709:25:
 In procedure ly:font-name in expression (ly:font-name font):
        
/home/consultant/lilynew/lilypond/out/share/lilypond/current/scm/lily-library.scm:709:25:
 Wrong type argument in position 1 (expecting Font_metric): 
        "CharisSIL"
        
3]  There is nothing special about CharisSIL,
        
        If I remove it, DoulosSIL takes it's place. I thinking that it
        might have something to do with fontconfig not understanding
        lilypond's font instructions and substituting a system font, I
        tried replacing the Ubuntu version of fontcong with the Debian
        "lenny"  version, but it makes no difference.
        
In addition to the above, there are some (possibly unrelated
font-related errors thrown up while compiling lilypond 2.13.12, For
instance:
