summary: |
<p>Get the codepoint of a character at character offset <code>char_offset</code>
of a string at <code>idx</code>. If the value at <code>idx</code> is not
a string, an error is thrown. If the string cannot be (extended) UTF-8 decoded,
the result is U+FFFD (Unicode replacement character). If <code>char_offset</code>
is invalid (outside the string) a zero is returned.</p>
example: |
printf("char code at char index 12: %ld\n", (long) duk_char_code_at(ctx, -3, 12));
