• LSL-2 sees all strings as UTF8
• LSL-Mono sees all string as UTF16
• llStringLength gets the number of characters
• Both UTF8 and UTF16 use multibyte characters
• Some communication functions (i.e. llHTTPResponse) are limited by number of Bytes, and work with UTF8 strings

    //remove 1 char from each escapable_byte's triplet.
