Log in by Name Failed from Devices with Name of No ASCII Characters

[songchenwen 0]

Newly log in by name failed on an iPhone. The device name contains no ascii characters. When I add several ascii characters to the device name, I can successfully log in.

 

I think the reason for this is that you remove all the non-ascii characters in device name during log in, which result in an empty device name.

 

A potential workaround is to use the device category like "iOS Device" or "Android Device" instead of the empty device name.

 

Logs below.

@@songchenwen, ah yes, good catch, thanks !

 

We need to revamp the way we transmit the device name from app to server, but this workaround will be fine in the meantime. Thank you.
