Problems sending an attached file with uuencode

I use uuencode in UNIX to send an attached .txt file to my e-mail.
The .txt file looks like this:

field_1;field_2;field_3
1;2;3
4;5;6
7;8;9
...

When the mail comes, with the attached file, it looks likt thuis:

field_1;field_2;field_3 ;1;2;3 ;4;5;6 ;7;8;9

The different lines are separated by a special return-sign the looks like a square. I try to paste a sample, but the square disappears.

I use this command:

uuencode HOME/test.txt test2.txt | mailx  -s "Test bestand" kdkdkd@de.be

Who can help me so the attached file looks the same like the original file?

This is common when transferring files to/from PC-based systems. Are you opening the file on a PC (your email)?

Yes, I am opening the file via Outlook
