If you need to test if a &binvar contains a UTF8 string, you can take advantage of the $regsubex feature where it can output a string into a binvar. If the input is $bvar(&var1,1-).text, you can test whether &var2 is created as an exact replica. Note how $isutf returns 0 for both binvars. On the other hand, the isbinvarutf alias returns 2 for &v1 which contains a UTF8 byte sequence, but returns 0 for &v2 because the cloned UTF8 output from $regsubex was not the same bytes as the original. Note that there's a limit to how long of a binvar can be tested using this method, because $regsubex only permits the $2 string to contain more than approximately $maxlenl *bytes* even when that string has fewer than 4000 UTF8 *characters*. | If you need to test if a &binvar contains a UTF8 string, you can take advantage of the $regsubex feature where it can output a string into a binvar.
