If you enable php error reporting, you will also get a warning that looks something like:

Which would confirm that PCRE lacking unicode support is the issue at hand

However, the only thing that can cause the all text being replaced with [1] thingy is PCRE missing unicode property support as far as I am aware, so I'm pretty sure that is the issue.

We are getting many reports of this issue with MediaWiki 1.19 (MW 1.19 is the first version that uses unicode regexes for parsing external links).
