From 7078556f9d055cb46339d436add2a03cc8abbc71 Mon Sep 17 00:00:00 2001 From: Lars Henriksen Date: Mon, 26 Mar 2018 18:44:08 +0200 Subject: Key bindings for UTF-8 encoded characters MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Internally characters (keys) have two representations: integers and key names. Key names are characters strings, usually the name of the character; e.g., the character A has the representations 65 and "A", and the tab character the representations 9 and "TAB". The function keys_int2str() turns the integer representation of a key/character into the key name. For display purposes the key names are usually confined to have display width at most three. Some curses pseudo-keys have longer key names; e.g., the back-tab character is "KEY_BTAB". A long key name makes a character difficult to recognize in the status bar menu. The key name of a multibyte, UTF-8 encoded character is the conventional Unicode name of the code point; e.g., the character ü has key name "U+00FC" because ü is the code point 0xFC. Most of these look alike in the status bar menu. The patch makes the key name of a multibyte character look like that of a singlebyte character: the character itself, i.e. the key name of the character ü is "ü". The main tool is implementation of a utf8_encode() routine.
