But を is "wo" (Hepburn romanization).
True, but I didn't think it was generally pronounced like that. I'll fix it.
And you can kill the つ (tsu) ones with "u"!? And there was another odd one... mmh.
Ah yes, that's a side effect of running out of space to code it properly. It's a little lax on the ones with alternative spellings. But I found a few bytes the other day, so I can probably handle this now.
Use one of the logical fonts such as Dialog instead. With a logical font you have a way higher success rate.
Changed the font to Dialog. Let me know if it works.
