MC-Basic:LEN

This function returns the length of the input  string as the number of characters in an ASCII-8 string, or the number of symbols in a UTF-8 string  .

In UTF-8 supporting versions 4.5.1 and higher NULL characters are no longer cut

out from strings, resulting in a different behavior:

-->?Len("A" + Chr$(0) + "B")

3.000000000000000e+00

Len of Chr$(0) is 1:

-->?Len(Chr$(0))

1.000000000000000e+00

In former versions NULL characters could not appear in the middle of strings, since

theconcationation process cut these characters from the resulting string.
