+Is there a way to support backslash or other "unusual" characters in
+the output .html names?
+
+I added `\\` to wiki_file_chars (not just `\` since this value is
+the contents of a Perl [...] regexp, per
+IkiWiki.pm). But doing this and then creating a file \foo.mdwn on the
+source side is not enough, because the backslash is autotranslated to /
+(for the sake of Windows I suppose), resulting in
+http://example.org//foo/.
+
+I'm looking to make a TeX-related wiki. Hence having backslash as a
+normal character is desirable. I know there would be plenty more complications,
+but, just exploring the options ...
+
+Generalizing from backslashes, is there a way to control the mapping
+from .mdwn names to the output .html names (and directories I guess),
+apart from the specific usedirs and indexpages settings?
+
+I've glanced through plugins and done a bunch of web searches without
+any success. Any help appreciated. Thanks. --[[KarlBerry]]
