I suppose the problem is in fact a confusion of what "echo" does with your variables.
"read" is always providing you with the full content of the line, but "echo" (as well as "print", etc.) will interpret your variables, which may change their content.
To prevent this, just enclose your variables in double quotes. Use one of your files and try the following code to see the effect between $line and "$line":
Code:
#!/bin/ksh
typeset line=""
typeset -i counter=0
cat <file> | while read line ; do
print - "linenr $counter raw : \"$line\""
print - "linenr $counter cooked: " \"$line\"
(( counter += 1 ))
done
