The pdf file has then this mapping with fi being named f_i and not fi (why

subsetted file.
I suspect that the pdf was created using glyph names and metrics for
Times, where fi and not f_i is used, but the font was not embedded. On
viewing the pdf, the font used instead of Times was the OpenType
version of TeX Gyre Termes, which has no glyph named fi. In this case
it should help to supply copies of the ligature glyphs using old style
names (fi and fl only).
Isn't it better then to install the standard ps set on the operating
system and make sure these are not remapped? The texgyre opentype fonts
are not supposed to be drop ins for those standard (15 or so) ps fonts.
I think even the type1 texgyre isn't by definition metric compatible. It
might be interesting to see how other viewers/operating systems behave
(e.g. do mupdf based viewers have the same side effect?)
I think that for that embedding the times and so is kind of mandate
nowadays. Those big cjk fonts are often extern but these have well
defined vectors. Personally I'd not spend a second on a user complaint
that concerns a not-embedded font.
(Btw, a bigger issue is actually that only a few viewers do 'copy' well
i.e. deal with tounicode vectors.)
