Summary:
The NSURLComponents header states:

"Although ';' is a legal path character, it is recommended that it be percent-encoded for best compatibility with NSURL (-stringByAddingPercentEncodingWithAllowedCharacters: will percent-encode any ';' characters if you pass the URLPathAllowedCharacterSet)."

However, NSURLComponents's own translation to NSURL does not behave correctly.

Steps to Reproduce:
Try the following code:

NSURLComponents *components = [NSURLComponents componentsWithString:@"http://one/two;three/four"];
NSLog(@"Path: %@", [components path]);
NSLog(@"Percent-encoded path: %@", [components path]);
NSLog(@"URL path: %@", [[components URL] path]);

Expected Results:
Path: /two;three/four
Percent-encoded path: /two;three/four —(or /two%3Bthree/four)
URL path: /two;three/four

Actual Results:
Path: /two;three/four
Percent-encoded path: /two;three/four
URL path: /two

Version:
Xcode 6 Beta 2
OS X 10.10 (14A361c)

Notes:
Workaround is to re-encode the percentEncodedPath.
