Combining dakuten and handakuten are U+3099 and U+309A. The precomposed glyphs are far more common, however.

si is /shi/, ti is /chi/, tu is /tsu/, hu is /fu/. wi, we, wo commonly romanized as /i, e, o/. their voiced dakuten forms zi, di, du are /ji, ji, zu/.

/sha, shu, sho/ and /cha, chu, cho/ are produced with si + yōon and ti + yōon. Also applies to /ja, ju, jo/, which are produced with zi + yōon.

A dakuten-voiced h-column kana becomes /b/, and a handakuten-voiced h-column kana becomes /p/. This applies to the fu-kana as well, which become /bu/ or /pu/.

A handakuten on k-column kana can be used to represent [ŋ], but typically don't bother.

/va vi vu ve vo/ can be represented with u + dakuten + small aiueo. (Typically just a b-kana is used for this.) Pedantically, /l/ can be distinguished from /r/ with a dakuten on r-column kana. Precomposed vu: katakana U+30F4 ヴ hiragana U+3094 ゔ

The small kana (marked in the tables with µ) are used for sounds foreign to japanese: ファ represents /fa/, ティ represents /ti/.
