Quick Overview

• string.split(str [,delim]) - Divides str into substrings based on a delimiter, returning a list of the substrings. The default pattern for the delimiter is white space (“%s+”).
• string.uchar(chnum, …) - Unicode characters may be included in strings by encoding them in UTF-8. This routine converts one or more Unicode character numbers into a UTF-8 string.
• string.usub(str, startpos, endpos) - This routine returns a substring of str. It is the Unicode version of string.sub. It accounts for multi-byte characters encoded in UTF-8. Caution: this is an expensive routine. It allocates a temporary memory buffer during its operation.
