Semi-colon Query

I saw this in my game's global chat history, and checked it out:

[OOC] Jiraiya: "Er. winky face. this client doesn't like semi colons"
[OOC] Azarial: "Which client?"
[OOC] Azarial (Azarial): "And you might try escaping the semi-colon"
[OOC] Jiraiya: "The one on the website"
[OOC] Azarial: "The fmud or the webportal?"
[OOC] Jiraiya: "Webportal"
[OOC] Azarial (Azarial): "Hmmm, interesting."
[OOC] Jiraiya: "The fmud didnt like it either tho"
[OOC] Azarial: "So it;s no ; or no background colours?"
[OOC] Azarial: "Ahh, I dind;t know that. that is an interesting flaw."
[OOC] Jiraiya: "It assumes semi colons and colons are line returns I think"

I believe this is viewed as a feature instead of a flaw that the client allows piping of commands. Our game has its own piping characters though (we use | internally), and we're an RP game where the use of ";" may be grammatically required for play. Can we get a way to disable this for our users by default?

Thank you!

Warm regards,

Can you link me to a little tutorial or how-to for setting up a custom code file?

Thanks oodles, plamzi!
