I don't think bare FreeType is not suitable for your purpose.
FreeType is a font renderer, doesn't provide features to convert
font formats nor to generate subsetted fonts. I think, using
cairo library to generate PS/PDF makes your task easy, because
cairo has font subsetting feature, and its API is similar to
low level PS command. However, its license LGPL 2.1 or MPL 1.1
is slightly more restricted than FreeType2.

I'm unfamiliar indepth of EMF, but I suppose there are only
Unicode encoded string and the name of font to display the string
in EMF. By "unicode characters", you mean the characters which
requires complexed text layout system (e.g. Arabic & Indic)?
If so, FreeType2 does not provide such, you have to choose a text
layout library (there are Pango, Qt, ICU and m17n).
For the affinity with cairo, pango or m17n might be better.

I know no good guidance of PS/PDF font embedding technology,
however everybody have to check
    Adobe Technote 5012: The Type42 Font Format Specification
