Inputs two keys. There are two types: those +# with a base character followed by an accent (see below for codes for +# accents), and those with a two-character mnemonic for the composed +# character. These are (with the exception of the Euro) the codes +# given by RFC 1345. Note that some codes in RFC 1345 require three +# characters to be input; none of these are handled. +# +# For best results zsh should have been built with support for +# multibyte characters (--enable-multibyte), but single character sets +# also work. +# +# Outputs the character converted from Unicode into the local representation. +# (The conversion is done within the shell, using whatever facilities +# the C library provides.) +# +# When used as a zle widget, the character is inserted at the cursor +# position. With a numeric argument, preview in status line; outside zle, +# print character (and newline) to standard output. +# +# The set of accented characters is reasonably complete up to U+0180, the +# set of special characters less so. However, it mostly gives up at that +# point. Adding new Unicode characters is easy, however.
