| | # Accented characters. 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. Please send any
# additions to zsh-workers@zsh.org .
#
# Some of the accent codes are a little more obscure than others.
# ! Grave
# ' Acute
# > Circumflex
# ? Tilde
# - Macron. (A horizonal bar over the letter.)
# ( Breve. (A shallow dish shape over the letter.)
# . Dot above, or no dot with lower case i, or dot in the middle of L or l.
# : Diaeresis (Umlaut)
# , Cedilla
# _ Underline (none of these currently)
# / Stroke through character
# " Double acute
# ; Ogonek. (A little forward facing hook at the bottom right
# of the character.)
# < Caron. (A little v over the letter.)
# 0 Circle
# 2 Hook
# 9 Horn
# Hence A! is upper case A with a grave, c, is lower case c with cedilla.
