Rewriting DOIs

One problem with my cunning plan to use Mediawiki REDIRECTs to handle DOIs is that some DOIs, such as those that BioOne serves based on SICIs contain square brackets, [ ], which conflicts with wiki syntax. For example, doi:10.1206/0003-0090(2006)297[0001:TATOL]2.0.CO;2 I want to enable users to enter a raw DOI, so I've been playing with a simple URL rewrite in Appache httd.conf, namely:

RewriteRule ^/wiki/doi:(.*)\[(.*)\](.*)$ /w/index.php?title=Doi:$1-$2-$3 [NC,R]

This rewrites the [ and ] in the original DOI, then forces a new HTTP request (hence the [NC,R] at the end of the line). This keeps Mediawiki happy, at the cost of the REDIRECT page having a DOI that looks a slightly different from the original. However, it means the user can enter the original DOI in the URL, and not have to manually edit it.
