t:urlDecodeUni

Description: Performs URL decoding on a string.

This transformation function is similar to t:urlDecode, but adds support for Microsoft-specific %u encoding. If the code point is in the FF01-FF5E range (fullwidth ASCII), the high byte is used to detect and adjust the low byte. Otherwise, only the low byte is used and the high byte is zeroed.

Syntax: t:urlDecodeUni

Implemented: Yes

Example:

SecRule ARGS "@rx test" "id:1001,t:urlDecodeUni"
