Welcome to the wonderful world of character sets and i18n.
You definitely want to keep the accented titles. Search doesn't work
properly for them on pmwiki.org, because the search page
(Main.SearchWiki) is in a group that is using iso-8859-1 encoding,
while the PmWikiVi page titles are encoded with utf-8. On a normal
PmWiki installation this really isn't a problem, because there the
entire site will typically be using the same encoding for all of its pages
and there the search will work just fine.

PmWiki is doing it because it must do so to be standards-compliant.
According to the standard for urls (RFC 2396), urls must consist of
characters only in the US-ASCII set; everything else has to be
escaped (http://www.ietf.org/rfc/rfc2396.txt, section 2.4):
Data must be escaped if it does not have a representation using an
unreserved character; this includes data that does not correspond to
a printable character of the US-ASCII coded character set, or that
corresponds to any US-ASCII character that is disallowed, as
The URI syntax was recently updated by RFC 3986, but even there it says
that non-US-ASCII characters in urls must be %-escaped.
There are many browsers which are able to handle non-US-ASCII
characters in urls, and RFC 3986 notes that these can work well
in local or regional contexts or with improving technology. But
there are still browsers that can't handle them, and since PmWiki
has a somewhat global perspective it chooses to follow the
published standards in this regard.
