Set a byte in a string.


string_set_byte_at(str, pos, byte);

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



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.


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".
