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
