IIS the_permalink and the ` and ' characters

[Frumph]

On IIS the ` and ' characters are not translating properly when the slug is created and then the url is made with pretty permalinks. When posts are made and title is clicked on it fails to find the page in question, however remove the ` or ' character in the slug and it finds it just fine.

Possibly non alpha characters doing it? Possible .htaccess redirect problem?

Would you mind explaining the steps to reduce the issue a bit further?

I am pretty sure you know how to put ' and ` in the slug for the permalink. IIS then cannot translate the permalink out properly so those characters for parts of the slug should be removed when its saved.

Kind of like how # and ? are not allowed to be used.

Not really :) I've just tried to create a post with "Sample Post '`" as a title in 3.0.4 (the initial reported branch) and in 3.3-trunk, and the permalink is sanitized to sample-post.

Is this really a bug ? I tried to replicate it in both WordPress and WordPress MS using IIS as the web server, but just as Sergey Biryukov said the slug is being sanitized correctly.

Can you provide more details ?

Feel free to reopen with more exact steps to reproduce if there's still a problem.
