Subject: [PATCH] Issue 4867: Ignore some major OpenType/CFF Collection (OTC)
 fonts

Current LilyPond cannot handle OpenType/CFF Collection (OTC) fonts
(NotoSansCJK.ttc and SourceHanSans.ttc etc.).
This commit is a workaround that ignores some major OTC fonts
for avoiding errors.
TODO: Add OTC fonts support and remove this settings
