That are outside the 7bit ASCII range, I am surprised this was not doneĬan we do something about it now, even if just documenting the current Given that Arduino originated in Italy, which uses some accented chars Such as when coding http servers, needs to more precisely defined or I think this issue of using non-ASCII characters for display purposes, Internationalisation means a consistent experience over various OS/locals. If I downloaded that sketch (or a library) on some other machine, what Testing back to your own terminal is not a valid test as the sketch isīeing run on the same OS/local that created it. Micro assembler, under an IDE with a simplified programming interface That is the main selling point of Arduino.

(looks at more then just 2 chars after \x) Note: UTF-8 in hex is not reliable due to the odd way C interprets it To convert non-ASCII chars to UTF-8 (in octal) for insertion into IDE Your OS and local and that of the machine where your sketch will be run.įor those cases that don't "just work" I will putting up a java program "Putting non-ASCII chars in your strings may just work, depending of We cannot just change the IDE to always read and write in UTF-8.

That is a 32-bit (formerly 16-bit) integer as opposed to the standard 8-bit char used for normal C strings. Note, this is completely different from wide string literals in C which are written with a capital L in front of quotation marks and use the base type wchar_t. Both encodings can be changed with command-line options to GCC. This removes any dependence on the current locale or compiler. For portability, it's common to specify non-ASCII literals as an escape like \u2182. For standard GCC on modern Linux systems, the machine encoding of any string literal is UTF-8, but the source file encoding is selected based on the current locale. Source files are parsed as characters in some source encoding (originally in either an ASCII or an EBCDIC encoding variant) and any non-control character excluding backslash and double quote can be included in a string literal verbatim and will be converted to the machine encoding when complied to an object file (machine form). There is a source encoding and a machine (binary) encoding for string contents. I am less well versed with C , but I know how C89 does it. > In data sabato 31 agosto 2013 15:31:07, Matthew Ford ha scritto: Ordinary-string-literal-and-utf-8-string-li C 11 added an "u8"īut it didn't work on avr-gcc, even if I try to use the compiler option ".
