iconv and sed help

Link to this post 21 Feb 11


I have a file which is a UTF-8 file type which i need to convert into ISO-8859-1 file type.

Now the UTF-8 file type contains characters like å/ä/ö and i dont want these characters.

So, i apply the sed command.

$ sed "s/å/aa/g; s/ä/aaa/g; s/ö/ooo/g" utf8.txt > output.txt

Now when i view this file, there are no such characters like å/ä/ö


i use iconv command to covert that UTF-8 (output.txt) file type into ISO-8859-1 file type

$ iconv -c -f UTF-8 -t ISO-8859-1 < output.txt > newfile


when i view the file type using file command it tells that its an ASCII file type not the ISO-8859-1

$ file newfile
newfile: ASCII text, with CRLF line terminators

I don't understand what went wrong. I have also attached that UTF-8 file with this post.

Please help.

I have went through your exact procedure on slackware 13.1 and my output file is showing as:
ut3.txt: ISO-8859 text, with very long lines

The way that the data is read and displayed may be controlled by a deeper configuration within your OS, can you share what distro you use so those familiar with it can tell you where those settings are?

I am so Sorry that i have attached the wrong file (actually both are of same name but in different folder on my machine).

This is the one which is causing the problem.

Now that I have processed your original file I am getting the same issue, it appears that something is different between the files.

The two files are very different. I have concatinated your command to

sed "s/å/aa/g; s/ä/aaa/g; s/ö/ooo/g" utf8.txt|iconv -c -f UTF-8 -t ISO-8859-1 -o out.txt

when I ran that command against both files I got the following output:

matt:~/Desktop$rm *.txt.txt;for i in `ls|grep utf|grep -v "txt\.txt"`;do sed "s/å/aa/g; s/ä/aaa/g; s/ö/ooo/g" $i|iconv -c -f UTF-8 -t ISO-8859-1 -o $i.txt ;file $i;file $i.txt;done
utf8.txt: UTF-8 Unicode text, with very long lines, with CRLF line terminators
utf8.txt.txt: ISO-8859 text, with very long lines, with CRLF line terminators
utf82.txt: UTF-8 Unicode text
utf82.txt.txt: ASCII text

Based upon the output it looks as though the line terminators in the second file are not ISO-8859-1 compliant, but the iconv applications does not correct those.
