Creates a thcrap repository from MediaWiki pages.
The {{stringdef}} template hook supports an |ascii mode which automatically transliterates any
non-ASCII characters to their closest ASCII equivalents when writing the text to the patch files.
This transliteration requires a language locale (i.e., not C) to be installed on the system that
runs this extension. Otherwise, any non-ASCII characters will be silently discarded.
Check TPCFmtStrings::onDef() for the hardcoded locale currently expected by the extension, which
should appear in the output of locale -a on the server.
