Found this quirk below while surfing.
Notepad displayed squares instead of the text on my machine.
This actually works. It will not crash your computer, it just breaks Notepad in that it causes it to display very oddly. No perm damage comes of the following steps.
Here's how to do it:
1. Open up Notepad (not Wordpad, not Word or any other word processor)
2. Type in this sentence exactly (without quotes): "this app can break"
3. Save the file to your hard drive.
4. Close Notepad
5. Open the saved file by double clicking it.
Instead of seeing your sentence, you should see a series of squares. For whatever reason, Notepad can't figure out what to do with that series of characters and breaks.

Apparently the same quirk is in Metapad and Notepad2.

It's because it saves as ascii and not unicode.

No, something about that phrase is tricking it into saving it as Unicode instead of ASCII.
Make two text files, one with the exact phrase, and another with the phrase missing one word... then view both with a hex editor. It's a bug.

Ah, so that's what it was. Though it's not the phrase, it's something about the number of characters input. Cause it works with "Bush hid the facts" too.

It works with:
abcd efg hij klmno
too, so it's obviously not the content, but the number, like you said.
They're just putting a stupid phrase about breaking the app to make it seem more credible

The IS_TEXT_UNICODE_STATISTICS and IS_TEXT_UNICODE_REVERSE_STATISTICS tests use statistical analysis. These tests are not foolproof. The statistical tests assume certain amounts of variation between low and high bytes in a string, and some ASCII strings can slip through. For example, if lpBuffer indicates the ASCII string 0x41, 0x0A, 0x0D, 0x1D (A\n\r^Z), the string passes the IS_TEXT_UNICODE_STATISTICS test, although failure would be preferable.
ahahahahahah, so A\n\r^Z will make it fail too
and 4 3 3 5 causes the test to fail as well
It's a limitation of Windows itself (the API for IsTextUnicode()), not Notepad.

Just for creeps, type in "Bush hid the facts". Big brother is spying on us?

Yeah, that's what it is. It's definitely not an exploit of the Unicode "guessing" API.
It works with "abcd efg hij klmno" too. Conspiracy? I think so.

hmmm...if it's about number and sequence of letters, then I'm guessing my quirk isn't related. Now and then when I open my homepage I get either those squares like you describe, or I get tons of symbols. I exit, wait 1 or 2 seconds, try again, and it's usually ok.

What browser, what homepage? Not a whole lot of programs use the Unicode guessing API, just ones that have to deal with saving and opening unmarked content (and most websites are properly marked with UTF-8, etc).

Hi DJ

Internet Explorer 6.0 and my home page is MSN.com
I have a picture of both errors I can put here - the squares and the symbols. This is probably really stupid, but I didn't know what if any info could be gotten out of what looks, to me anyway, like a mess, so I was hesitant to post it until I asked you. Is it ok to post them? and would they be helpful? Or do you know what I mean without seeing?

Hope this works

<sigh> why is everything so difficult
These were originally 370kb so I shrunk them. I thought you could click on them and enlarge, but I can't. Have no idea what to do

Once you resize them, they're resized permanently. Start a new thread about this problem and post the full images, unresized. Save your screenshots as PNG in the future, they will be a lot smaller (even mspaint.exe can save PNG). A 1152x864 screenshot using PNG is only 134 KB for me.

Screw it. Thanks for trying to help, Dj. But my limit for attachments on this site is 236 and I don't know of any way to shrink the screenshots. I've tried a few things, but everything makes them bigger. They're both over 350.
If it happens again - which it will eventually - I'll save the screenshots as png.

That's what I'm saying - take the screenshots again as PNG, and they will fit under the limit.
