Although some versions of sed accept backslash escapes for octal, hexadecimal, and common character escapes like \n for <newline> and \t for <tab>; none of these are present in "standard" sed.
The sed command needed to change Latin capital letter A with acute to Latin capital letter A is simple:
but this works if, and only if, your current locale is using the same codeset that is used to encode Latin capital letter A with acute that is present in lalo.txt. Based on the od output you showed us in post #1, we can say that Latin capital letter A with acute is encoded correctly for the ISO/IEC 8859-1 codeset in lalo.txt. And based on the other posts you have made in this thread, my guess would be that your current locale is using UTF-8 as its underlying codeset. Therefore, the following printfj command should create a sed command that will do what you want:
If you run the above command and then run the command:
you should end up with the file lalo2.txt with the output you want, as shown by the command:
The LC_ALL=C is probably needed because the ISO/IEC 8859-1 encoding of Á found in lalo.txt is not a valid character in the codeset used by your current locale. The LC_ALL=C will cause that sed command to be run in a locale where every single-byte value is a valid character. This should avoid the errors like:
that you might get without it.
