Grid does not display special characters (as square boxes)

Question

SQLD 1.5.1 (54.40):
We found out, special characters like newline will not shown in data grid in any way. But we need to know, if there are such characters. If there any way to get these characters visible?
Pls try following case
create table mytab (mycol varchar2(20));
insert into mytab(mycol) values('Test'||char(13));
commit;
select * from mytab;
You will not see the appended newline character within the grid, while toad is doing .

Answer 1

You're right that whitespace doesn't show as squares anymore (I think they did in the past), but everything else seems OK.
Why don't you try something like this and prove for yourself:
select '     
!"#$%&''()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~€‚ƒ„…†‡ˆ‰Š‹ŒŽ‘’“”•–—˜™š›œžŸ ¡¢£¤¥¦§¨©ª«¬®¯°±²³´µ¶·¸¹º»¼½¾¿ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõö÷øùúûüýþÿ' from dualRegards,
