Does anyone have a "valid" character set for use with the Arduino IDE compiler?
I am working on a project that needs a minimum of 98 unique characters. I have found 95, but there must be more that I don't know about.
My board is set to: "ESP32 Dev Module"
I can specify each character as follows: char myChar = 'a';
The problem I have is that if I try to use a char that the compiler doesn't like then the compiler exits with an error and does not compile my programme.
(e.g., char myChar = '€';
I assume there must be a documented character set somewhere, I just haven't been able to find it.
All help is appreciated, thanks.
