Since the CFString branch seems to stay for a while, here are some improvements
to its fromUnicode().

- properly combine surrogate pairs coming from CFString;
- normalize the string to NFC (canonically composed form).

I don't think any browser actually does the latter, but this is obviously more
important on Mac OS X than on Windows. If Mail.app uses this code, this may
correct problems with sending files having accented characters in their names
to Windows recipients.

form-data-encoding.html has been modified to cover more Latin-1 cases, and
another case has been added for UTF-8.
