ENCODING GUIDE 1. Most UTF-8 editors display the file encoding. 2. If you’re unsure about the encoding of your data or cannot display it correctly in a text editor, if the file is not too big try opening it in your standard text processing program (e.g. Microsoft Word or Open Office) to find information regarding the encoding. 3. Windows machines: install Cygwin from https://cygwin.com/install.html • COPY your .txt files to your Cygwin user directory and then: $ file *.txt • Depending on the output, list all possible encodings: $ iconv -l • And re-encode (e.g. Windows Hebrew to UTF-8): $ iconv -f CP1255 -t UTF-8 in.txt > out.txt 16/100
