Describe the problem

The M5Atom library contains extended characters that cause compilation errors when using the Arduino CLI on a gitlab pipeline with debian. The error occurs due to the use of non-standard quotation marks in the M5Atom.h file. A suggested fix can be found in the section 'Additional context'.

Environment:

Arduino CLI Version: arduino-cli version 0.19.3
ESP32 Core Version: esp32:esp32 3.0.0
M5Atom Library Version: 0.1.2
Operating System: Debian (used in CI pipeline)

To reproduce

Install 'M5Atom' library using the Arduino CLI.
Attempt to compile any sketch that includes the 'M5Atom.h' file

Expected behavior

Compilation fails with the following error

/root/Arduino/libraries/M5Atom/src/M5Atom.h:82:8: error: extended character “ is not valid in an identifier
82 | #error “This library only supports boards with ESP32 processor.”
|        ^
/root/Arduino/libraries/M5Atom/src/M5Atom.h:82:64: error: extended character ” is not valid in an identifier
82 | #error “This library only supports boards with ESP32 processor.”
|                                                                ^

Arduino CLI version

arduino-cli version 0.19.3

Operating system

Linux

Operating system version

Debian on pipeline

Additional context

Current suggested fix:

Run the following commands to replace the invalid characters before compiling:

sed -i 's/“/"/g' /root/Arduino/libraries/M5Atom/src/M5Atom.h
sed -i 's/”/"/g' /root/Arduino/libraries/M5Atom/src/M5Atom.h
