Sanitizing non-English letters to use safely in URLs

Question

What is the best way, in .NET, to create safe URLs from titles of posts? For example, I may have a post "test wıth non enğlİşh çharaçters" and I want to turn this into a URL safe form while still maintaining the readability purpose of the title being URL, such as, "test-with-non-english-characters", and I will use them as http://mysite/blog/5/test-with-non-english-characters I can just iterate over the string characters and either leave ALL letters as they are (not safe to use in URLs), or wipe out all non-English characters and turn them into an underscore etc. (breaks the purpose of readability, as posts will/may be in non English languages). I'm sure that there's a method for converting ş to s and Ğ to G etc. just like in an accent insensitive search query in SQL server.

This is probably a losing battle. What lowercase letters does ڟﻌ▓░♀☺╩ۆ correspond to? — Rag, Aug 18 '11 at 15:15
they would be removed. anything that doesn't have an accent insensitive mapping to a letter in the English alphabet would obviously be removed, I don't think I need to say that explicitly. — Can Poyrazoğlu, Aug 18 '11 at 15:26

See my answer to another question to remove accents from a string.

Note that this doesn't completely solve the problem. For example, Asian ideograms or non latin letters will not be transliterated to english (latin) letters using this code.

for now, just latin accent removal is enough for me. i didn't know about the `Normalize` method, i think it will work for me.. – Can Poyrazoğlu Aug 18 '11 at 15:32
