Cannot support Chinese paths and file names about arduino-ide HOT 1 OPEN

Hi @Chenjiek. Thanks for your report.

Arduino cannot support Chinese paths, file names

It will not be possible for us to investigate the problem based on such a vague description. I need you to provide the following information:

• Detailed instructions we can follow to reproduce the fault
• Detailed description of the fault that occurs when you perform those instructions, including the full and exact text of any error or warning messages you encounter.

and variable names?

Variable names are handled by a standard C++ compiler, and thus limits on them are those imposed by the compiler, not by Arduino IDE. You can learn about the subject here:

https://en.cppreference.com/w/cpp/language/identifiers

Note that the compiler may impose even more narrow limitations than what is permitted by the C++ specification, per this note on the page linked above:

Note: Support of Unicode identifiers is limited in most implementations, e.g. gcc (until 10)

from arduino-ide.
