When installing MediaWiki (1.17+, with the new installer) on Sourceforge, it gives a fatal error: "PHP's PCRE module seems to be compiled without PCRE_UTF8 support. MediaWiki requires UTF-8 support to function correctly." I don't know much about the problem or PCRE itself (maybe this is a Sourceforge-specific problem), but it's possible to install MW 1.16 on Sourceforge, and then upgrading to trunk so it should be possible to install 1.17+ or trunk directly.
The check is there because some stuff* is broken without it. *Someone else can hopefully clarify what stuff.
Well we use unicode in some of our regular expressions, so we need support for it. If 1.16 installed without checking this then that's the old installer's fault for not being robust enough.

INVALID since 1.16 is no longer supported.
