Compile issue with ESP8266 core 3.0

[henmel]

Thanks for a geat library!
When trying to compile the example sketch E131_Test.ino, I get the following compile error:

\Arduino\libraries\ESP_Async_E1.31/RingBuf.h:50:18: error: extended character “ is not valid in an identifier
   50 |         #warning “This library only fully supports AVR and ESP8266 Boards.”

The sketch comiles and runs fine on the core 2.7.4
