Yes but the "funny" Thing is, 0x1F is the only one(?) one can enter by keyboard....and so very tricky if somebody hits Ctrl instead of Shift.
Can you tell me how to move all this from Lunge to discussion...I seems I choosed the wrong place

I don't think you have. This is the most sensible thing I've read here in days.

I agree with Phil!
I dunno if you got any "abuse" votes for it: you can check in your Rep history by clicking the current rep number in the top right of the page. But if you need it moved, AFAIK only the staff can do that, so you'd have to ask nicely in Sugs'n'Bugs.

I would be happy if it would not exist, but there are some rare Winform apps still running in this world. So imagine somebody typed in this crap by mistake and it will be stored to the database...
You are right, nobody needs that, but it exists.

Ain't it the case for about 90% of things that exist ?
About the 0x1F, aren't the entry going some plausibility check before being put in the database ? It is not a valid xml char, so running the string through an xml validator would throw an error.

Agree. It is odd that the control allows this, but we should always do some kind of validation on any user input (users are stupid after all --  ) since we know users like to enter things that are forbidden.

I agree, but who is expecting something like this? Even DataGridView has same behaviour and who does validate really in that deep.

I agree with you that it is ridiculous that the textbox or datagridview text would accept these non-printable characters. Makes no sense to me.

And the story goes on, if you want to annoy colleagues:
a.) Windows Login Dialogue where one can enter username, you can also type an unvisible "Ctrl&_" on colleagues PC and check how long he Need to find out what's wrong.
b.) I also played a little bit with that in the Windows Registry, very unusual things can be produced by "Ctrl&_"
N.B:
- WPF seems to handle this better, what I tested until now.
- In Web Browser Front Ends "Ctrl&_" is usually Zoom and so no failure deteced until now.

Just remembered that my sql server admin was attempting to set password in Sql Server mgmnt studio and even though he would set it to the value I sent him I could never log into sql server using my password. Finally found out he had some invisible char in there.
Very interesting. This is surely the same problem.

I liked this as a topic in lounge.
Interesting and I can tell you aren't just looking for an answer, but are talking about this in general as an topic that people might sound off on.
Upvote!

Interesting behavior, thanks for sharing! Indeed, hidden characters are a b*tch! This is a great example of something a user might accidentally do.
Kind of related...the other day I needed to use the ¢ symbol in a description and had to lookup the old alt+0162 trick that I hadn't needed in years!

First of all - a
German chauffeur on his passage to execution - Schumacher, obviously
pointless - sphere
is joined by his old - hisold
which gives aschumacherhisoldsphere. I ignored the "no" because it does not fit, and you have probably made a mistake in the letters count.
