URL decoding on IIS

[qmpeople]

Hello,
I'm having some problems with decoding urls on IIS6.
When I click on URL UTF-8 encoded, resulting querystring replace any non english chars with question marks. Why? I use UTF-8 encoding in my pages !!! Thank you

You'll find better help in the IIS forum, to which I've moved your thread.

Please show us a same url you are using?

Yes sure,
for example, if you open http://www.qmpeople.com/ you can see a link in the middle of the page http://www.qmpeople.com/tag/%D1%84 containing an UTF-8 char properly encoded . If you click on it, target page shows incorrect querystring "404;http://www.qmpeople.com:80/tag/?"
In fact, unicode char has been replaced with a question mark. Why? I'm becoming crazy because I alredy tried a tons of different solutions.
As you can see I use a 404 custom handler to manage all tags and all pages involved use UTF-8

Thank you for your help

Not sure if this helps:
encoding programs

Thank you but... http://www.qmpeople.com/tag/%D1%84 is already correctly written in UTF-8 encoding.
I think that there's no simple solution.... : (

Very strange... I just discovered that If I write http://www.qmpeople.com/tag/?%D1%84,
my querystring is shown properly. I'm becoming crazy..

[kenobewan]

If it works why fight it :). May be that ? usually references a querystring, so that http://www.qmpeople.com/tag/ is read as the url and then %D1%84 as the information string. If this is what you intended, then my fault for not picking this up earlier...

Hello kenobewan,
I don't want to use ? for SEO....
In addition I already created some other tags with the same format(hostname/tag/tagname) and I prefer to maintain the same style.
It's very strange because IIS6 fully support UTF-8 url encoding :(
