If you are running on 10.4 or later, you can use CFStringTransform.

CFStringTransform(myMutableString, range, CFSTR("Hex-Any"), NO);

"Hex-Any" is equivalent to "Hex-Any/Java", and the \u style is the one used in Java.

Hello list.

My code receives NSStrings containing unicode hex escapes that start with asterisk (*) instead of backslash (\), and I need to decode these strings. For example, I need to convert @"hello*u0020world" to @"hello world".

Using NSMutableString replaceOccurrencesOfString:withString:range: to convert @"*" to @"\\", yields @"hello\u0020world" as expected, but I can't seem to get from there to @"hello world".

I realize that \u0020 is neither percent-escaped nor UTF-8 encoded. I've tried searching this list's archives, and the web in general, all tried the variants of stringByReplacingPercentEscapesUsingEncoding: and stringWithCString:encoding: I can think of. I scanned the CFString docs, but none of the functions jumped out at me.

So, how does one convert from @"hello*u0020world" to @"hello world", short of parsing the hex sequences?

Thanks.
