The video appears to have a CNS / 国标 date – do we know what the user’s region settings are ?
Apart from the CJK glyphs, the Chinese pages of Unicode have addresses for various special versions of roman letters, local punctuation, etc etc – I wonder if any of those are turning up in the .bike file ?
