ASCII... Well, the UTF-8 character set is indeed designed to be backward compatible with ASCII but it is far more than that -- and even these days many programmers do have trouble with UTF-8. Why? Because UTF-8 is a multi-byte, variable length character encoding system. Sure, the backward compatible ASCII codes are single byte but you can literally encode any character defined by UNICODE via UTF-8. Chinese characters defined in UNICODE take more than a single byte to define so they require the multi-byte features of UTF.8.
Now, I do agree that the programming for radio control is not likely to run into multi-byte characters but UTF-8 will include them if they are found elsewhere -- say a text file that has mixed English as other multi-byte characters. I agree with the need to download Xcode and learn Objective-C but the new Swift language might be easier for someone who is just starting out to learn. I am not sure which would be easier to learn, Objective-C or Swift but I think Swift, being more modern and also supporting scripting is easier. 73, phil, K7PEH > On Feb 21, 2015, at 9:30 PM, Jack Brindle <jackbrin...@me.com> wrote: > > ASCII?
