Sets the default encoding for FileRead, FileReadLine, Loop Read, FileAppend, and FileOpen().
FileEncoding , Encoding
One of the following values (if omitted, it defaults to the system default ANSI code page, which is also the default setting):
UTF-8: Unicode UTF-8, equivalent to CP65001.
UTF-8-RAW: As above, but no byte order mark is written when a new file is created.
UTF-16: Unicode UTF-16 with little endian byte order, equivalent to CP1200.
UTF-16-RAW: As above, but no byte order mark is written when a new file is created.
CPnnn: A code page with numeric identifier nnn. See Code Page Identifiers.
The built-in variable A_FileEncoding contains the current setting.
Every newly launched thread (such as a hotkey, custom menu item, or timed subroutine) starts off fresh with the default setting for this command. That default may be changed by using this command in the auto-execute section (top part of the script).
The default encoding is not used if a UTF-8 or UTF-16 byte order mark is present in the file, unless the file is being opened with write-only access (i.e. the previous contents of the file are being discarded).
