Show only fonts which support a certain codepage

I’m writing greek, german and english texts. Trying to find a font for the greek part is difficult, because not every font installed supports the greek unicode codepoint. It’s difficult to find the one with greek codepoint due to the fact that the font manager has an implicit fallback to a default font whem a character isn’t found in the selected font.
Is it possible to show (as an option) only those fonts that supprt this codepoint (e.g. selectable in the language combobox)?
Thank you
