In an offline discussion, jr helped me work through my own confusion 
with the .ttc support in POV-Ray.

I tried the 'CJK' .ttc fonts blindly on seeing the .ttc suffix.

Well, it turns out OpenType fonts also use the .ttc suffix and POV-Ray 
doesn't support them. I didn't know. My Ubuntu distribution puts the 
OpenType fonts in another directory:

/usr/share/fonts/opentype/noto/NotoSansCJK-Regular.ttc

rather than:

/usr/share/fonts/truetype/

but I didn't notice...

If you are on linux and have the .ttc collection in a personal directory 
you can use the 'file' command:

file NotoSansCJK-Regular.ttc

and it will kick out text about the file. Part of which will includes 
detail on the internal font types stored. For example:

NotoSansCJK-Regular.ttc: OpenType font collection data, 1.0, 10 fonts, 
at 0x34 OpenType Font data, 16 tables, 1st "BASE"

or 'file LiberationMono-Regular.ttf' :

LiberationMono-Regular.ttf: TrueType Font data, 18 tables, 1st "FFTM", 
30 names, Macintosh

So, I'm leaving the .ttc support in place with yuqk and I'll add yuqk 
documentation that the POV-Ray support for .ttc files is only for 
TrueType collections.
