This is the selection I am using. Just “Hiragana”. However, if you write ichi and start changing it you sometimes get two 1s with these symbols next to it: 半/全
Those symbols are, as you might know, half and full width, respectively.
Would it help if I sent the project or uasset to you? Just tell me how to send it.
