Here's a link to an uncompressed (using pdftk) PDF:
https://dl.dropbox.com/u/35611549/test_uncompressed.pdf
I honestly have no idea what I'm looking at when I open that in Emacs.
Here is info about the Junicode ligatures that can't be searched:
glyph name f_t, encoding U+EECB
glyph name f_t_y, encoding U+EED0
glyph name f_r, encoding U+EECA
That's exactly the problem - these glyphs are encoded at PUA codepoints,
so that's what (most) tools will give you as the corresponding character
data. If they were unencoded, (some) tools would use the glyph names to
infer the relevant characters, which would work better.
Small caps are named like "a.sc" and they are unencoded.
And as they're unencoded, (some) tools will look at the glyph name and
map it to the appropriate character.
The font is
generated by FontForge. The PDF is generated by XeTeX (XeLaTeX
actually). I don't know if another program (e.g. LuaTeX) would yield
different results.
