Latin
ʉ is normally replaced by i, since it only occurs in zʉ~zi, cʉ~ci and sʉ~si

ɵ can be put as ø or oe if not available and ʉ can be put as ue, although ʉ is practically never used

Tone is put via diachritics (平-入: a, 上: á, 去: à) and 阳 register is put with an h before the coda or uh or ih if u or i was the coda
