declaimed the following in comp.lang.python:

Then Open the Notepad and type the following sentence, and save the
file and close the notepad. Now reopen the file and you will find out
that, Notepad is not able to save the following text line.
Well you are speed
This occurs not only with above sentence but any sentence that has
4 3 3 5 (sequence of characters: Well=4 you=3 are=3 speed=5)
I tried. I also opened the saved file in SciTE...
And the text WAS there...

It is Notepad that can not properly render what it,
itself, saved.

C:\Documents and Settings\mensanator\My Documents>type huh.txt
Well you are speed

Yes, file was saved correctly.
But reopening it shows 9 unprintable characters.
If I copy those to a new file (huh1.txt):

C:\Documents and Settings\mensanator\My Documents>type huh1.txt
?????????

But wait...the new file is 20 characters, not 9.

09/16/2007 01:54 PM 20 huh1.txt

C:\Documents and Settings\mensanator\My Documents>dump huh.txt
huh.txt:

Here's what it's actually doing:

C:\Documents and Settings\mensanator\My Documents>dump huh1.txt
huh1.txt:
00000000 fffe 5765 6c6c 2079 6f75 2061 7265 2073 .~Well you are s

One word: Unicode.

The "open" and "save" dialogs allow you to specify an encoding.

And the encoding specified was ANSI.

If you
specify Unicode the you will get what you see above.

And if you specify ANSI _before_ you click the file name,
the specification switches to Unicode and has to then
be manually switched back to ANSI.

If you specify ANSI
you will get the text you entered.

It's still a bug in the "open" dialog.

It's more like a bug/feature in its encoding detector. I can get it to
switch to Unicode only if there's an even number of characters AND the
line is NOT terminated by CRLF -- add/remove one alpha character, or
hit the enter key at the end of the line, and it won't detect it as
Unicode when you open it again.

You only get the BOM (0xfffe) if you are silly enough to save it while
it's open in Unicode mode.




By the way, this has precisely what to do with Python?

I've been known to use Notepad to create Python
source code.

Your source code would have to be trivially short to trigger the
strange behaviour.
