Description

PrintToChatAll("\x001White \x004Orange"); doesn't seem to work anymore with the latest SM dev build (chat message not printed at all). But it worked properly last months with a few older SM builds. \x1 and \x4 are working but if I am trying to output \x4Binary it will take the color as \x4B and I don't want that. There is also a way to PrintToChatAll("\x1White \x4%s", "Binary"); that works nice however it's going to require tons of args and I don't like the idea.

Could you test out if trying a build prior to #2255 fixes your issue ? That's version 1.13.0.7197 or earlier, and if your issue does go away, try version 1.13.0.7198 and see if it breaks again.

1.12.0-git7162 (3bc55e6) is latest working build. Since 1.12.0-git7163 (0a6fa10), trying to print "\x001Hi,\x004 Orange" won't print anything. As download link, I used https://sm.alliedmods.net/smdrop/
I am not sure if the problem is compile.exe/spcomp.exe related or sourcemod_mm.dll or other modules.

Edit: Looks like latest VS for C/C++ allows now up to 4 digits/A-F after the \x prefix. If specified less than 4, the following A-F-starting words will be messed up (if no space between \x4 and the word).

Edit: Found alliedmodders/sourcepawn@20a28c6#diff-3333d1260ba153b3897c84af7ea3bbdb955bb50f7a79783a9ad51f728717a86fR2138 ; So I get that older edition took up to 3 digits, actual edition up to 2, but C/C++ allows up to 4. Anyways, it's up to you to decide a correct limit. Started this issue because I didn't know at first what really happened.
