Add support for Unicode Phonetic Extensions and Phonetic Extensions Supplement Unicode blocks

[topological-modular-forms]

[...] the Unicode Phonetic Extensions and Phonetic Extensions Supplement blocks are of potential interest in a number of linguistics contexts (especially when it is preferable to use a local phonetic alphabet instead of the IPA), and most fonts don’t have full coverage (if they have any coverage at all).
