Problem with encoding unicode

[Peter O'Doherty]

Hi,
Not all unicode characters are being correctly realised in my score. Something like \mark \markup { \char ##x03EE } will work but this throws an error:

\mark \markup { \char ##x1080B }
error:

programming error: FT_Get_Glyph_Name () error: invalid argument

continuing, cross fingers

programming error: Glyph has no name, but font supports glyph naming.

Skipping glyph U+1001080B, file /home/peter/lilypond/usr/share/lilypond/current/fonts/otf/CenturySchL-Roma.otf

Does anyone have any idea what the problem is?

Many thanks,
Peter
