Does it link correctly with special characters if you use the official Tuya Smart app?

Hi,
have you successfully reproduced the issue ?
Can it caused by "string substitution patterns" like "%d" "%s" "%f" … ?

Sorry, this slipped through the cracks.

It's possible the device is expecting ASCII encoding instead of the UTF8 that we're currently doing. To test that theory, we would have to edit

link/lib/link.js

Line 156 in 7df3e5e

const wifiPasswordBytes = Buffer.from(options.wifiPassword);

and

link/lib/link.js

Line 159 in 7df3e5e

const ssidBytes = Buffer.from(options.ssid);

to look like Buffer.from(..., 'ascii'). Might also have to then change

link/lib/link.js

Line 261 in 7df3e5e

_getLength(str) {

, but I think that should work as-is.

It's not a huge priority for me ATM, but if you or someone else wants to see if that fixes it I can merge in the changes.
