When JMP’s system setting is Charset("utf-8"), how can a variable be automatically saved as a txt file in Charset("gb2312") format?

[#1]

Is changing the system setting to Charset("gb2312") the only way to save a variable as a txt file in Charset("gb2312") format?

On a 64-bit Simplified Chinese Windows 11 system.
Thanks!

Yes, except I think there is an exception if a file is opened in the jsl editor from a gb2312 encoded file. Saving that editor window back to the *same* file might use the original file's charset.
I think savetextfile() also has a charset parameter, you might search the scripting index ... I think there might be another function that uses an explicit charset.

edit: Only loadTextFile() and open() have the charset option, for reading. Wish list here:  charset for saveTextFile

Thanks Experts!

Preference( Open Text File Charset( "gb2312" ) );
Preference( Save Text Files as Unicode( 0 ) );
Save Text File( 径1, 新文);
Preference( Open Text File Charset( "utf-8" ) );
