#### 4.9.34 UTF8IO ¶

Syntax: `UTF8IO [0|1]`
Abbreviation: `U8IO`

sets the UTF-8 input/output flag. This flag is set automatically depending on your locale setting, and is used to determine whether communication with the user (keyboard and terminal) should be UTF-8 encoded. Normally you would not alter this flag, but sometimes `ne` may make the wrong guess (e.g., when you are remotely connected).

If you invoke `UTF8IO` with no arguments, it will toggle the flag. If you specify 0 or 1, the flag will be set to false or true, respectively. An ‘`@`’ will appear on the status bar if the flag is true.
