mlterm(Multi Lingual TERMinal emulator)

A mechanism would be helpful for absolute positioning of output on top of a
right-to-left line.
Currently, if a program tries to draw a menu, using graphic menu border
characters and cursor positioning escapes, the bidi reordering seems to be
applied after all output, thus mangling the menu appearance. (As a
workaround, the application must clear all right-to-left lines before
opening a menu...)
Unicode control characters that are intended to control this behaviour
(e.g. U+202A LEFT-TO-RIGHT EMBEDDING) are ignored.

(This may be a limitation of the underlying fribidi library, I don't know,
so it might be hard to handle by mlterm alone.)
