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.
