## vim:ft=zsh
## This snippet serves two purposes:
##  - it offers a central place to manage 'special' characters
##  - it's used to enable / disable unicode
##
## The parameter unicode decides whether unicode is used or not,
## the default is to use unicode.
##
## In the associative array chars, the 'special' characters are stored.
## Each entry contains two characters, the first is ASCII,
## the second may be unicode.
##
## To get a ascii-/unicode-char, the function zchar is used, which outputs a
## character based on the setting of the unicode parameter
##
## disable unicode: unicode=0; reload
## disable ALL unicode, even in PS4 and such: unicode=0 zsh
##
## Note: This only affects zsh, for other programs set $LANG or similar
