Have you tried something like this:
NSString *EncodeForHTML(NSString *input)
{
unsigned length = [input length];
unichar *buffer = malloc(length * sizeof *buffer);
if(buffer)
{
NSMutableString *result = [NSMutableString string];
for(unsigned i=0; i<length; ++i)
{
if(buffer[i] >= 'a' && buffer[i] <= 'z' ||
buffer[i] >= 'A' && buffer[i] <= 'Z' ||
buffer[i] >= '0' && buffer[i] <= '9')
{
[result appendFormat: @"%c", buffer[i]];
}
else
{
[result appendFormat: @"&#x%x;", buffer[i]];
}
}
free(buffer);
return result;
}
return nil;
}

Subject: Translating accented characters to HTML entity equivalents
I have a need to convert accented characters (such as A) to their HTML
entity equivalents (Á) in an NSString. I am at a loss as to
how to do this.
The reason: I need to send the HTML entity equivalents instead of the
characters so that they get sent correctly through the web services
methods.
The problem: When I convert ordinary entities - such as < into < -
it works just fine. When I try to convert, say, A to Á it
doesn't work - it sends it as the accented character, and it gets
mangled and delivered incorrectly on the endpoint of the webservice.
I've tried converting it to a double-encoded entity - e.g., sending it
as &acute; - which, according to NSLog, is how WebServicesCore
actually sends < - but it makes no difference at all.
Note that if I type Á into a text field and send it that way,
it works great - it gets translated into &Aacute; and works fine
on the other end - it's only when I try to change A behind the scenes
that it fails to work.
The current code: Inefficient, I know. We have an NSString, theText.
NSArray *tmpArray = [theText componentsSeparatedByString:@"A"];
theText = [tmpArray componentsJoinedByString:@"Á"];
Any ideas?
