While on the forum of a server I use, I saw that someone had created a thread saying that the percent sign doesn't show up in the chat. I joined a server I regularly use and logged in, and then typed % in the chat and pressed the enter key. I saw my name in the chat but only empty space next to it.

Does anyone know the answer? I do recall something about a certain character not being usable in the chat - I think it was because of a security-related issue - but I'm not sure.

Security Issue with coding.

Ah, okay thank you.

Really annoying. This can't be fixed?

Well not really afaik else they would've fixed it already? Anyways you can use % in your gamemode for example like this:

pawn Код:

new String[128];
        
format(String, sizeof(String), "100%s", "%%");
SendClientMessage(playerid, 0xFFFFFFAA, String);

This would show in the chat: 100%

'%' get's replaced by '#' right or was it '?'? Perhaps you can fetch '#' or '?' under OnPlayerText then replace it with % using the above method but I never tried that.

I think in <0.2X it was replaced with '?', now it's replaced with a space.

I don't see why it's not fixable though, the server could replace it with '%%' if it's being formatted.

You could try doing a lot of stuff with strfind though, and replace the string.

From the wiki:

%% Inserts the literal '%

I'm unsure if it'd detect the % sign at OnPlayerText though. If so, try using strins to insert the '%%' into his msg?

if a player enters things like %d, %f or %s then they could fuck up all the formated strings.

That is the reason why it got blocked. And replacing % with %% wouldn't help(still %%s).


Replacing it with a secret text serversided could work and then a clientsided script wich replaces this text again with a '%'.

Did you try this? The reason '%%' is there is so '%' appears in a formatted string. '%' is merely an escape character like '\' is an escape character for Pawn strings which you escape with '\\'.

I would like to see '%' allowed back in chat again. It's easy to make counter measures against format attacks by filtering the string before parsing it into format, any half-decent scripter would know how to do this. I'm sure someone would post a generic function to do this for newbies anyhow.

The answer is given on a silver platter, right here in this topic:

What more explanation do you need?
