Added support for unicode string (ustring) tag.
Add support for ustring tag
I've never seen a ustring tag before. Can you show me an example? I added some unicode characters to a regular string tag using Xcode's plist editor and it was saved as a regular string tag.
Don't see an example of a "ustring" tag either
The purpose of the library is to facilitate working with the plist format. If you can provide an example of Apple emitting a tag feel free to re-open the pull request. It's a well written pull request, just hard to see how it fits into the library.
