Generic way to sanitize url by stripping any special char

OK, great. Now try to transform this 'sanitized' URL back?

Some religious rules disallow you use urlencode()?

By the way, do you happen to know this guy?)

@dimasmagadan Hi,

The short answer for not using urlencode is yes, I know about it and I don't want to use it.

For more explanations, the reason is that I need to build a unique URLs index and I don't care about retrieving the original title from the URL, but with these function I can filter all url variations and be sure that urls are not the same :

• case sensitive
• ignore any accents
• removing tags
• remove special chars
• (optionnaly) only alpha numerics
