将包含3字节ASCII字符的NSString编码为正确的NSString

Question

A JSON request returns strings with an HTML encoded Unicode character.

It looks like this: valószínű which should be decoded to valószínű

In other words ű should be ű .

I found a description about a list of non-standard HTML characters here: http://www.starr.net/is/type/htmlcodes.html

Is there any easy way to correct this?

Answer 1

It appears that the string is partially escaped. If you encode "valószín&#369" into an NSData object using:

NSData * data = [@"valószín&#369" dataUsingEncoding:NSUTF8StringEncoding];

then created an attributed string using

NSAttributedString * attrString = [[NSAttributedString alloc] initWithHTML:data documentAttributes:nil];

the "u" will be properly converted, but the preceding marks would be mangled:

resulting in

valószÃnű

An alternative would be to see the following post:
