When a WLAN with WPA2 PSK is configured in the Wireless LAN Controller GUI which format is supported?

Unicode is a broader character encoding that includes ASCII but is not typically the specified format for WPA2 PSK passphrases, which are often limited to a subset.

Base64 is an encoding scheme used for binary-to-text conversion, not the direct character set specified for WPA2 PSK passphrases.

Decimal refers to a numeric system and is not a character encoding format used for wireless passphrases.

WPA2 PSK (Pre-Shared Key) passphrases, when configured via a Wireless LAN Controller GUI, commonly support ASCII characters. This ensures broad compatibility and interpretability across various devices and systems adhering to wireless security standards.
