Email Link HTML Encoding Problem

[martin]

When creating a link of type "E-mail", upon entering content into the subject or body field if a british pound symbol (£) is entered the resultant html for the pound symbol becomes "%C2%A3" which displays "£" when decoded.

The problem can easily be fixed by going through the source and removing "%C2" everywhere it occurs, but this then breaks the link editor.

This can be replicated on the nightly build of the editor.

Confirmed with IE6 and FF2.

Hi,

This is actually the correct behavior.

According to ​RFC3986, data in URL components should be encoded in the UTF-8 format.

Now, if you look at ​Section 3 of RFC3629, you'll see that for unicode code points in the range [0x80, 0x7ff], which includes the British pound symbol, the code point value would be split over two bytes.

So, according to the formulae given in the RFC, the British Pound symbol, at unicode code point 0xa3, which is 10100011 in binary, would be split into 11000010 10100011, which is 0xC2 0xA3 in hex. So the maths is correct, and thus the URL encoder in FCKeditor is doing what it is supposed to do.
