This template is no longer in use as it results in poor readability. Converts a UTF-8 string to folded case (lowercase), which can be used to compare two strings. If input is an integer, it's treat as a code point and a convert code point (integer) is returned.
Syntax
string|int utf8.lower ( string|int input ) string|int utf8.fold ( string|int input )
Required Arguments
- input: A string character sequence OR an integer value
Returns
Returns a string in lowercase OR returns an integer (see description).

ServerThis example shows how to convert a string to lowercase, which can be used to compare with other folded strings.
local output = utf8.lower( "WHAT ARE YOU UP TO? Do you like uppercase?" ) print( output ) -- what are you up to? do you like uppercase? local value = utf8.fold( 1088 ) print( type( value ) ) -- number
