# ALT/META CHARACTERS
By default, foot prefixes meta characters with *ESC*. This corresponds
to XTerm's *metaSendsEscape* option set to *true*.
This can be disabled programatically with *\E[?1036l* (and enabled
again with *\E[?1036h*).
When disabled, foot will instead set the 8:th bit of meta character
and then UTF-8 encode it. This corresponds to XTerm's *eightBitMeta*
option set to *true*.
This can also be disabled programatically with *rmm* (Reset Meta Mode,
*\E[?1034l*), and enabled again with *smm* (Set Meta Mode,
*\E[?1034h*).
