If this flag is set then a Unicode space character is represented using the \fBTERMKEY_SYM_SPACE\fP symbol. If this flag is not set, it is represented by the U+0020 Unicode codepoint.

If this flag is set then an ASCII DEL character is represented by the \fBTERMKEY_SYM_BACKSPACE\fP symbol. If not, it is represented by \fBTERMKEY_SYM_DEL\fP. An ASCII BS character is always represented by \fBTERMKEY_SYM_BACKSPACE\fP, regardless of this flag.
