Available since LÖVE 0.9.2 |
This module is not supported in earlier versions. |
This library provides basic support for handling UTF-8 encoded strings.
It provides all its functions inside the table returned by require("utf8")
. This library does not provide any support for Unicode other than handling UTF-8 encoding. Any operation that needs the meaning of a character, such as character classification, is outside its scope.
For detailed usage, see the reference manual.
The utf8.char function does not work correctly in 0.9.2; However, it is not an issue since 0.10.0 |
Examples
Print text the user writes, and erase it using the UTF-8 module.
local utf8 = require("utf8")
function love.load()
text = "Type away! -- "
-- enable key repeat so backspace can be held down to trigger love.keypressed multiple times.
love.keyboard.setKeyRepeat(true)
end
function love.textinput(t)
text = text .. t
end
function love.keypressed(key)
if key == "backspace" then
-- get the byte offset to the last UTF-8 character in the string.
local byteoffset = utf8.offset(text, -1)
if byteoffset then
-- remove the last UTF-8 character.
-- string.sub operates on bytes rather than UTF-8 characters, so we couldn't do string.sub(text, 1, -2).
text = string.sub(text, 1, byteoffset - 1)
end
end
end
function love.draw()
love.graphics.printf(text, 0, 0, love.graphics.getWidth())
end
