Encoding problem in non-ascii characters

CMDHELPER-3171 - Reported by bexco2010

If we(non-ascii users) write non-ascii character(which is hangul(korean) in my case), CommandHelper won't show correct letters on UTF-8 Encoded File. This means If code is transfered to another computer which uses diffrent encoding(EUC-KR to EUC-JP for example), code with non-ascii characters will shows broken letters when executed.

So, CommandHelper needs to set default encoding to UTF-8 for non-ascii users.

I attached photo which shows I tried to message "안녕" to player in UTF-8 Encoded MethodScript file.

plus, If try to send non-ascii message to console(tmsg() or console() function), It shows broken message.
please check console output with non-ascii characters, too.

Thanks.

issue 中没有指定文件或测试。首先，在 UTF-8 的 MethodScript 文件中使用韩文复现该问题，包括通过 tmsg() 或 console() 发送的消息；当脚本执行时以及其代码在使用不同编码的计算机之间传输时，非 ASCII 字符都能保持正确，即表示完成。
