Understanding
Clearly, every text file has an encoding, that means, you must know if two bytes form one character to display, one byte, or the characters have mixed byte length. Unicode defines every character in the world.
Here is some practice: Store a file containing
hellö world
in file.txt. Do:
tweedleburg:~ # cat >file.txt hellö world tweedleburg:~ # cat file.txt hellö world tweedleburg:~ # hexdump -C file.txt 00000000 68 65 6c 6c c3 b6 20 77 6f 72 6c 64 0a |hell.. world.| 0000000d
This means, every "normal" character has been stored in 1 byte, every umlaut in 2 bytes. That is unicode's UTF-8 encoding.
Doing
Convert a file to UTF-8
convmv -f iso-8859-1 -t utf8 -r --notest <datei> recode latin1..u8 <datei>
Unicode text editor:
- yudit
