cmunrm.otf uses "unstandard" names for the glyphs of the old style
numbers, e.g. oneoldstyle. 

This means that the glyphs don't get a tounicode mapping:

\pdfvariable compresslevel=0


6 beginbfchar
<0042> <0061>
<0043> <0062>
<0044> <0063>
<0874> <FFFD>
<0875> <FFFD>
<0876> <FFFD>

The names are in glyphtounicode.tex, which contains e.g.

So it doesn't looks as if they were completly unusual. Would it be
possible to add tounicode mappings for these name?

And how can one declare mappings for really unusual names?
