I wasn’t aware of those calls. They do not seem to be deprecated. However, I have also a lot of accented characters (é, à, û, etc.) to unescape (since the contents are in French), and CFXMLCreateStringByUnescapingEntities() provides a basic dictionary of only five elements; it is extensible, but of course at the expense of creating a custom dictionary, which, added to the necessary conversions between CFStringRef and NSString and vice-versa, would hamper the legibility of the code somewhat.

Yeah, that’s what I thought of. I will add a note in the body of the article about this.
Thanks for all!
