AdiIRC will automatically use PCRE2 if available, although it can be disabled by typing [[/setoption]] Misc UsePcre False, in this case AdiIRC will fallback to .NET regular expressions.

AdiIRC uses the .NET regular expression engine, while mIRC uses the PCRE engine, some differences are converted from PCRE to .NET while others are not possible.
