Subject: [PATCH] Fix the issue where the localization information is set
 before the program calls the 'utf8_decode' function in the project code.
 After calling the 'utf8_decode' function, the restored localization
 information is the default setting from the user environment variables,
 rather than the current program's localization information. Therefore, the
 'setlocale(LC_ALL, "")' call should be changed to 'setlocale(LC_ALL, NULL)'
 to align with the code logic.
