Caveats
- The index of the last character is not equal to the string length.
- Character indexs start at zero (the index of the first character is zero).
- llStringLength() gets the number of characters, not bytes
- LSL-2 sees all strings as UTF-8
- LSL-Mono sees all string as UTF-16
- Both UTF-8 and UTF-16 use multibyte characters
- Some communication functions (e.g. llHTTPResponse) are limited by number of Bytes, and work with UTF-8 strings
- To quickly find out the number of bytes (in UTF-8), you can use llStringToBase64 (see also snippet there)
Examples
// assumptions:
// object name: LSLWiki
// script name: _lslwiki
default
{
state_entry()
{
string HowLongAmI = "123";
integer strlen = llStringLength(HowLongAmI);
llOwnerSay( "'" + HowLongAmI + "' has " +(string) strlen + " characters.");
// The owner of object LSLWiki will hear
// LSLWiki: '123' has 3 characters.
