Tips
To insert an UTF-8 character given its unicode codepoint nnnn using bash:
> printf '\ucea9'
Ω
Or using utf-8 encoding (e.g. \u03a9 → 0xcea9)
> echo -e "\xce\xa9"
Ω
In vim, in insert mode, to insert
- a BMP unicode character:
<C-v>unnnn(with 0000 ≤ nnnn ≤ ffff) - any Unicode character:
<C-v>Unnnnnnnn( with 00000000 ≤ nnnnnnnn ≤ 7ffffffff)
