Unable to Change Parameters with non-standard ASCII

[FUNNYPOTATO64]

I wrote this in Edit a Command window:
/avatar/parameters/更衣室:i 5

when I say the spoken command, voiceattack would recognize the command but VRChat would not change the integer value in the debug menu. Resulting in no outfit changes.

I wrote those kanji letters by using LINE's OCR and pasting it to the command.

This image (as shown in the screenshot) is from OSC debug menu inside of VRChat

I hope you could look into this problem. Thank You.
