Hi there!
We're trying to fix some holes in a language filter we have on our network.
Since the IRCd does not "know" the ASCII codes for text highlighting, it simply passes them through the filter and they can be used to evade it.
Does anyone know the specific ASCII codes for all of the various graphical highlighting methods in mIRC, that are sent to the IRCd?
We've tried a sniffer and a dump, but it all apears as "normal' text.
Any help would be appreciated!

Bold (ctrl-B) = $chr(2)
Color (ctrl-K) = $chr(3)
Normal (ctrl-O) = $chr(15)
Reverse (ctrl-R) = $chr(22)
Underline (ctrl-U) = $chr(31)

Thanks...but that's not what we're looking for. =\
We have that list already.
The ASCII should look something like "0133," or "0166," etc.

Umm what he gave you is ASCII codes.
Bold is ASCII code 2
Color is ASCII code 3
etc.

None of those codes work, though, so they must not be correct. 002, bold 031, itallics 022, reverse Nadda...

OK, we seem to have it under control with bold, but not underline or reverse, which is odd.
Also, it started to work when we combined our filter mode with +c...not sure what other alterations were made.
Still looking into it. Any ideas are welcome. =)

022 and 22 are not the same thing. When you use 022, you are talking about an octal number, 22 is decimal. In octal, 22 would be 026 for example.

I'm told it needs to be three letters/characters. 22 does not work.
I really have no idea how the IRCd looks at codes. I'm not the one programming this, I'm relaying what is said here to one of our network/server admins. =)

Well who ever told you an ASCII code has to be 3 digits doesn't know what he is talking about.

Quoth I: No it does not, but the extended code we use for IRC does.

Well I don't have any idea what this guy is talking about. I've been programming an IRCd for the last 3 years, those codes work perfectly for me. If they don't work for you, then talk to the people who are familiar with your particular IRCd. The codes you were given are the ASCII codes, if you want something different, then there's nothing I can do for you.

Would that IRCd be Unreal?
We use Bahamut.

Yes it would be Unreal. And, I'm rather familiar with Bahamut code, and it does not have anything to the effect of "ascii codes must be 3 digits." ASCII codes are NOT required to be 3 digits, as I said, if you're going to tell me they are, then you need to go and get help from whoever is telling you this, because he is the only one who can help you.

We have so many blasted modifications to the IRCd and services I can't name them all. It may be some custom bit that she coded...so I don't know. I will find out.

I haven't a clue - I mentioned she should post here, not me, but I didn't recieve a reaction. ASCII by itself does not have to [have three characters], but extended characters like BOLD and them typically do. *shrugs*

Bold is NOT an extended ASCII character. Bold is ASCII code 2. Extended ASCII codes are those with codes between 128 and 255 inclusive, not ASCII code 2. This is the last I am posting on the issue, this is now pointless.

Anyway, just in case, if you're looking for the octal values: 002 (bold), 003 (colour), 017 (plain), 026 (reverse) and 037 (underline).

The triple digit is the octal escape code for a character. The C compiler sees "\003" as "3" in base-8.

No kidding, I already said that. However it is meaningless for codes 2 and 3 because they are exactly the same value in decimal and octal.
