At least, in order to avoid broken glyphs,
we will need to change whether or not embedding by the font type.

i.e.
TrueType   : no embedding
Type1 / OTF: embedding

So `-dEmbedAllFonts=false` cannot be used.
Perhaps, `/NeverEmbed` and `/AlwaysEmbed` can be used.
However, I've never tried it. It is just an idea.

Moreover, we will need to change font resource directory
depending on the font type.

i.e.
Japanese OTF: <fontresourcedir>/CIDFont/
Other fonts?: <fontresourcedir>

But, I have another idea.
It does not need the font resource directory.
To use a PostScript file which only contains font resources.
It is one PostScript file and includes

`%%BeginFont`
~
`%%EndFont`

blocks of all necessary fonts.
I'm trying it.

Anyway, I think there will be a lot of things to consider.
