When trying to use an URL that includes the hash (#) character. The Web Agent (by default) is changing this character and it writes the encoded version of the character.
An example below:
> Original URL
> Changed URL
Webagent 12.52SP1CR04 on Apache 2.4 - Redhat 6
By Default with 12.52 and above webagent with do some Localization and will try to encode/decode the complete URL, it is true for accented but also for special chars
Set the ACO parameter:
> Localization = No.
