I know in ASCII '\r' is 0x0d,'\n' is 0x0a.
But some say ASCII characters in UTF8 is unchanged.
Now I want to know in UTF8 '\r' and '\n' are already 0x0d and 0x0a??
Could anybody can tell me? Very Thanks!!!! 16 2744

That's correct. All ASCII characters (0x00 to 0x7f) are unchanged in
UTF-8. All Unicode values from 0x80 up are encoded into 2, 3, or 4 bytes
that never reuse 0x00 to 0x7f.

Wasn't that the other way around on Macs?

<shrug> depends what you mean by '\r' and '\n'. :-)
On a Mac, a text file's end-of-line indicator (C89 draft 2.1.1.2)
is 0x0D. When this is read into a C program, it is translated into
a '\n' character.
If anyone's got a Mac with a C compiler, could they please tell us
what this program prints on that system?
#include <stdio.h>
int main(void)
{
printf("\\\r = %d\n", '\r');
printf("\\\n = %d\n", '\n');
return 0;
}

Probably not what you think. ;-)

ITYM:

int main(void)
{
printf("\\r = %d\n", '\r');
printf("\\n = %d\n", '\n');
return 0;
}
Which outputs:
\r = 13
\n = 10

No, the actual values of '\r' and '\n' are unchanged on the Mac. The
difference was when reading/writing a file in text mode on a MacOS
before 10. (As of 10, the UNIX convention has been adopted; i.e. text
mode and binary mode are identical).

I expected as much, but since I haven't used a Mac since 1989, I
didn't want to risk making an idiot of myself. (Seems I did that
anyway, in a rather unexpected direction.)

True, <cr> is 0x0D and <lf> is 0x0A would be better description.

#include <stdio.h>
int main(void) { printf("\\r = %d\n", '\r'); [corrected] printf("\\n = %d\n", '\n'); [corrected] return 0; }
Metrowerks 3.0, Mac IIvx, swap \n and \r enabled...
\r = 10
\n = 13
The compiler option allows mac implementations to avoid having
to perform runtime translations of text file end-of-lines.

Does ASCII characters remain unchanged under UTF8????Since it
unchanged,Why I can't printf thme in screen?
I use libcap get the FTP commands from Ethernet.I have one class to
get all packages and flowed,buffered them,Then aonther class can
readline (ended with \r\n)from buffer.Every time I readline from buffer
to get a command.
When I use CuteFTP I can get all commands an printf them in
screen.But when I use IE to FTP I can see one command "set utf8 on" and
then next commands I can't printf them in screen.Should I conver utf8
to ASCII?:( This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Hi all,
I'm creating a fixed length textfile with data which is sent out to a
third-party which in turn reads the file and processes it. Some of the
characters are not part of the lower ASCII table. This causes problems
because an È (&HC4) in the textfile is converted into 2 bytes on the
receiving end which then in turn shifts the remaining data on the line one
byte to the right... and in a fixed length textfile that's a disaster

I read the content from a file encoded with UTF8 like this:
byte data = binaryReader.ReadBytes(file.Length);
And next step, I want to transform data to ASCII format, How can I do
this?
You know, Using Encoding.UTF8.GetString(data) can get a ASCII string,
but I need a byte.
I hope you get my point. Any suggestion will be appreciated.

Hi,
Is there a string function to trim all non-ascii characters out of a
string?
Let say I have a string in python (which is utf8 encoded), is there a
python function which I can convert that to a string which composed of
only ascii characters?
Thank you.
