# *utf8* library
|
|
|
|
The library provides functions for working with UTF-8.
|
|
|
|
```lua
|
|
-- Converts a UTF-8 string to a Bytearray or an array of numbers if
|
|
-- the second argument is true
|
|
utf8.tobytes(text: str, [optional] usetable=false) -> Bytearray|table
|
|
|
|
-- Converts a Bytearray or an array of numbers to a UTF-8 string
|
|
utf8.tostring(bytes: Bytearray|table) -> str
|
|
|
|
-- Returns the length of a Unicode string
|
|
utf8.length(text: str) -> int
|
|
|
|
-- Returns the code of the first character of the string
|
|
utf8.codepoint(chars: str) -> int
|
|
|
|
-- Returns a substring from position startchar to endchar inclusive
|
|
utf8.sub(text: str, startchar: int, [optional] endchar: int) -> str
|
|
```
