Arduino IDE Character Set

Hello everyone,

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.

C (Arduino) character set is ASCII...

There are many other characters sets, you can google "unicode" for example.

So, I see from the table that I have found them all, there are only 95 usable characters - what a bummer.

So use Unicode... where are they being displayed?
