[Error] An error is caused if the source code contains English characters

Included in the original code

public static string[] SplitStringByComma(string input)
{
string[] splitStrings = input.Split(new char[] { '，', ',' });

return splitStrings;
}

After FSR processing

public static string[] SplitStringByComma(string input)
{
string[] splitStrings = input.Split(new char[] { '��', ',' });

return splitStrings;
}

No problem if don't use Chinese characters

Start with the SplitStringByComma entry point shown in the report and reproduce the issue using the Chinese comma character. Trace the FSR processing that changes the character to � while preserving the ASCII comma. Done means the Chinese character remains intact after processing and inputs without Chinese characters continue to work.
