Originally created by @LennartVin on GitHub (Feb 15, 2022).
Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/1360

I have set up the simple example. However, when I click on a network where the SSID includes a "-" and try to connect to it, I receive the error stating "AP not found".
I can connect to the SSID when I enter the SSID manually. This means that by clicking on the SSID on the Connection site the SSID is not correctly transferred to the textbox

What version ?
Did you try the newest beta?

Or did this just start?

I have this issue too. More specifically on the ESP32, newest beta (haven't tested with other versions yet).

this makes no sense!

Upload

*wm:[3] Method: POST
*wm:[3] [ARG] param s test–dashes
*wm:[3] [ARG] param p 12345678
*wm:[3] Sent wifi save page 
*wm:[2] processing save

It cannot be a coincidence, but I still cannot figure it out

I reverted that, I added it because IDF was having issues, and now this is.. string looks clean, Ill need to check the length of the c_str and termination maybe.. and make sure there is refs here

Just reading on this. The issue I had with not connecting to WiFi using PlatformIO (https://github.com/tzapu/WiFiManager/issues/1358) is probably the same issue.
Since reading this I have pulled the new beta into PlatformIO and everything works again.

Same issue Dash in SSID is converted to e28093 #1372
there is something that converts the - into a multi byte character, this prevents the SSID to be found
#1372 contains some more analysis
I will try the current beta if it fixes it.

It still worked in 2.0.5-Beta
In 2.0.8 and 2.0.9 it failed.

I did not check yet with 2.0.6 and 2.0.7.
If I do, I will try to update the info.
For now I have at least a workaround.

I think this was still working but the character was ignored, I will refix this properly now, I will test it again maybe it depends on esp libs
