bug#20499: [PROPOSED PATCH] C-x 8 shorthands for curved quotes, Euro, et


From: Paul Eggert
Subject: bug#20499: [PROPOSED PATCH] C-x 8 shorthands for curved quotes, Euro, etc.
Date: Sun, 3 May 2015 18:13:10 -0700

Although C-x 8 lets you insert arbitrary Unicode characters, it's
awkward to use this to insert commonly used symbols such as curved
quotes, the Euro symbol, etc.  This patch adds simpler sequences for
ISO 8859-15 characters (which includes the Euro), plus characters that
are commonly found in English text and in basic math.  For example,
assuming the Alt key works on your keyboard and iso-transl is loaded,
one can now type "A-[" instead of "A-RET LEFT SIN TAB RET" to get the
character "‘" (U+2018 LEFT SINGLE QUOTATION MARK).
* doc/emacs/mule.texi (Unibyte Mode), etc/NEWS: Latin-9 and a few
other printing characters now work too.
* lisp/international/iso-transl.el (iso-transl-char-map):
Also support ISO 8859-15 characters (e.g., "€"), plus the characters
"–—‘’“”†‡•′″←→↔−≈≠≤≥" which are commonly used in English text
or basic math.
This patch is a followup to Bug#20385; although it is a separate issue
and does not fix Bug#20385, it could make fixing Bug#20385 easier.
