Digraphs

screen supports the entry of non-ASCII characters via the digraph command. You can use octal or hexadecimal numbers for the characters, if you know the numeric codepoints you want, but the two-character mnemonics are probably easier to remember. The characters can be entered in any order, so “a"” is equivalent to “"a”; both will make an a-umlaut.

screen's digraphs are a rough amalgamation of RFC 1345, with additional digraphs for many characters. They only cover the ISO-8859-1 charset. There is a patch for stricter and more-complete RFC 1345 digraph support at http://aperiodic.net/phil/screen/screen-rfc1345-digraph.patch ; that patch still only supports digraphs (RFC 1345 also includes a set of variable-length mnemonics), and the order of character entry is significant.

The digraphs that screen understands are as follows. RFC 1345 digraphs are in bold.
