 =head1 RXVT-UNICODE VS. RXVT
 Unlike the original rxvt, B<rxvt-unicode> stores all text in Unicode
 internally. That means it can store and display most scripts in the
 world. Being a terminal emulator, however, some things are very difficult,
 especially cursive scripts such as arabic, vertically written scripts
 like mongolian or scripts requiring extremely complex combining rules,
-like tibetan or devenagari. Don't expect pretty output when using these
+like tibetan or devanagari. Don't expect pretty output when using these
 scripts. Most other scripts, latin, cyrillic, kanji, thai etc. should work
 fine, though. A somewhat difficult case are right-to-left scripts, such
 as hebrew: B<rxvt-unicode> adopts the view that bidirectional algorithms
 belong into the application, not the terminal emulator (too many things --
 such as cursor-movement while editing -- break otherwise), but that might
 change.
 If you are looking for a terminal that supports more exotic scripts, let

+me recommend C<mlterm>, which is a very user friendly, lean and clean
 terminal emulator. In fact, the reason rxvt-unicode was born was solely
 because the author couldn't get C<mlterm> to use one font for latin1 and
 another for japanese.
 Therefore another design rationale was the use of multiple fonts to
 programs force onto its users never made sense to me: You should be able
 to choose any font for any script freely.
 Apart from that, rxvt-unicode is also much better internationalised than
 its predecessor, supports things such as XFT and ISO 14755 that are handy

 rxvt. This all in addition to dozens of other small improvements.
 It is still faithfully following the original rxvt idea of being lean
 and nice on resources: for example, you can still configure rxvt-unicode
 without most of its features to get a lean binary. It also comes with
 from within a single process, which makes startup time very fast and
 drastically reduces memory usage. See @@RXVT_NAME@@d(1) (daemon) and
