Thx for the link.
I do hope this can be integrated into the future updates.
On iOS software keyboard i can do this by holding the punctuation block. It offers various style of punctuations.
On both Mac and Windows, there is an option for this in native input method.
Even on Linux, it is there in Fictx IME.
But with bluetooth keyboard, it become impossible to type halfwidth punctuation.
Actually, it can be done by a long-holding, but you get a series of full width punctuations with some half width punctuations (depends on how long i press the key).
Feels like the bluetooth keyboard is just a roughly mapping for the software keyboard.
