Rewrite rule to remove all non alphanumeric symbols from a URI

I could not find the exactly the same question on SO. I hope someone can help me out with this.

Say, user entered http://www.example.com/abc#!def, and what I want to do is remove all symbols in the ${REQUEST_URI} portion, then do a redirect to http://www.example.com/abcdef. The problem is that these symbols can occur anywhere in the string, e.g. #ab!cdeg and abcdef#! should both redirect to abcdef.

If I'm correct, there is no string replace function for mod_rewrite, so this seems impossible to do, but am I correct?

You can capture specific parts of an URL with regular expressions in a RewriteCond or RewriteRule, but not remove arbitrary characters.

Furthermore, you will never see the hash character '#' and everything after it in a URL, because it is used by the client to navigate to a specific part of the document.

Update using the next flag:

RewriteRule (.*)[^a-zA-Z](.*) $1$2 [N]

This rule removes all characters, which are not ^ alphabetic.
