string_set_byte_at

string_set_byte_at

Set a byte in a string.

Syntax:

string_set_byte_at(str, pos, b)

Argument	Description
string str	The string to change the byte of
int pos	The position within the string (starting at 1) to change the byte of
byte b	The new byte value

Returns: string

Description:

This function sets a byte directly in a string (based on the UTF8 format) and returns a copy of the string with the changes.

NOTE: This function is incredibly slow so consider carefully whether it is necessary and where you use it.

Example:

string str = string_set_byte_at("hello", 2, 97); 

The above code would change the byte value of the second letter in the string, and so set the variable "str" to hold "hallo".
