append single character to NSMutableString

There's stringWithCharacters, stringWithUTF8String, and stringWithCString depending on what you've got to feed it. Makes no difference how long it is.

If your character is stored in a 'unichar' variable then you can do:

unichar ch = 'A';
[myMutableString appendString:[NSString stringWithCharacters:&ch length:1]];

How about

{yourString stringByAppendString:@"A"}?

where {} are [] (somehow when I use brackets the string inbetween will be striked out >_<)

@"somethingHere" creates a NSString from something here as far as I know. Sounds likes the easiest solution

Format code on this forum like this:

my code here

<-- no slash

This solves the strikeout and link issue.
