When adding a new post/page in WordPress the title auto converts to a safe URL for the permalink, i.e. spaces become hyphens, accents and strange characters are removed and so on... For example:
Title:
This is my favourite post
Generated permalink:
http://example.com/this-is-my-favourite-post
The problem is that when using ampersands (or other non alphabetical characters) they disappear:
Title:
Black&White best designed websites
Generated permalink:
http://example.com/blackwhite-best-designed-websites
What it should be:
http://example.com/black-white-best-designed-websites
Which cause the two keywords (black, white) to become one (blackwhite) loosing the keywords in the URL. Same happens with forward slashes and other characters like JavaScript/jQuery becomes javascriptjquery.
Would be helpful if some characters (/, &, @...) where converted to hyphens.
Cheers :)
