# 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.
