special characters in wifi password

RouterOS Wireless Networking

Good morning
a customer asks me to put a strong wifi password made up of special characters. can you give me a list of allowed characters?
I configure the wifi via the following script set up in a custom configuration.

if I use this example password %9B/txfgm;6wX! with the script below, the router crashes.
Can you help me ? Looking forward, thank you in advance

/interface wireless security-profiles set [ find default=yes ] supplicant-identity=MikroTik
/interface wireless security-profiles add authentication-types=wpa-psk,wpa2-psk eap-methods=“” management-protection=allowed mode=dynamic-keys name=Wifi_Sec_Prof supplicant-identity=“” wpa-pre-shared-key=“****" wpa2-pre-shared-key="”

i think a long enough pseudo-random key using case sensitive alphanumeric is enough (cracking it with todays technology take centurys) without the hassle of special characters

using special characters is searching for troubles with some client devices

same thing with SSID’s

of course if “your customer” real desire is to pose a challenge he have made it

Hello, I have just found the beginning of an answer by inserting backslashes in front of each of the special characters but the router continues to crash. So I think that certain special characters are accepted without backslash and not others hence my first post to find a list to accept or not the router
