URL 'special character' replacements

[Claude Henchoz]

Hi guys

I have a huge list of URLs. These URLs all have ASCII codes for special
characters, like "%20" for a space or "%21" for an exclamation mark.

I've already googled quite some time, but I have not been able to find
any elegant way on how to replace these with their 'real' counterparts
(" " and "!").

Of course, I could just replace(), but that seems to be a lot of work.

Thanks for any help.

Cheers, Claude
