Construct a single character string from the supplied Unicode value.
Returns a string
| • integer | val | – | Unicode value for character. |
This function returns a single character string generated from the character at the indicated UTF-32 codepoint.
If val is negative, the codepoint has no valid single-character UTF-16 representation such as a part of a surrogate pair, or is outside defined range, the Unicode replacement character "�" (0xFFFD) is returned.
If val is 0, an empty string is returned.

Examples

{
touch_start(integer total_number)
{
string test_string = "The quick brown fox jumped over the lazy dog";
list test_list = [];
string test_string2 = "";
integer index;
integer ord;
for (index = 0; index < llStringLength(test_string); ++index)
{
ord = llOrd(test_string, index);
test_list = test_list + [ ord ];
}
string char;
for (index = 0; index < llGetListLength(test_list); ++index)
{
ord = llList2Integer(test_list, index);
char = llChar(ord);
test_string2 = test_string2 + char;
}
llSay(0, "\"" + test_string + "\" -> [" +
