Embedding a specific set of characters for a language

Hi,
I am creating a multilanguage application, and I am trying to find the best way to use the correct character set for each language.
My languages are English, Italian, Russian, Portuguese, Polish, Romanian, Spanish, German. I want to use Myriad, that seems to contain all the necessary glyphs, but I’d like to import just the need ones for each language, or to create a library containing all the glyphs needed by all languages (if the size is acceptable).
Now I am wondering if there is a site or some kind of resource that lists the needed characters for each language, so when embedding the font I can always import the Numerals, Punctuation, Lowercase and Uppercase sets, plus the language-specific glyphs, listing them, and avoiding additional sets that may contain more glyphs than needed.

Thanks
