The Wikipedia has the following information about this codepoint:
Sa (hiragana: さ, katakana: サ) is one of the Japanese kana, which each represent one mora. Both represent [sa]. The shapes of these kana originate from 左 and 散, respectively.
Like き, the hiragana character may be written with or without linking the lower line to the rest of the character.
The character may be combined with a dakuten, changing it into ざ in hiragana, ザ in katakana, and za in Hepburn romanization. The pronunciation is also changed, to [za].
