The Source Pro fonts should fully support Pinyin, which is a Latin-based representation of Chinese. The Source Han fonts also support Pinyin. Zhuyin, which is more commonly referred to as Bopomofo, is a completely different script, and is used mainly in Taiwan. The Source Han fonts support this script, and we made huge improvements to its glyphs and support in Source Han Sans Version 2.000. Pinyin should work in our apps, as does Bopomofo as long as tones aren’t necessary.
