The txt file with the content opens properly in the GUI editor (i am using sublime). But in vim, it appears like this, now i can't do the grep in this file. When i use less, it says "may be a binary file". How do i convert this to proper text file. Any idea why these strange characters are appearing?

It looks like a plain text file stored in Unicode UTF-16 LE, where each Unicode codepoint stored as one or two 16-bit code units.

If the text itself is primarily ASCII-only (all codepoints ≤ U+00FF), the result looks as if a NUL byte was inserted after every byte, if you're viewing the file from an UTF-16-incapable editor.

In command line, use iconv -f utf-16le -t utf-8 < file.txt > file-new.txt to fix it.

In Vim, you can use :e ++enc=utf-16le to re-open the file using the proper encoding.

If possible, tell Sublime to save files as UTF-8, which will be much more compatible with various tools. (In Vim: :set fileencoding=utf-8 | w)

Actually, ASCII text would be all code points ≤ U+007F. – dotancohen Apr 18 '14 at 14:37
Right, miscalculated. – grawity Apr 18 '14 at 14:51
Thanks. I also found a command that stripped all the unknown char from the file tr -cd '\11\12\15\40-\176' < input-file – Anjesh Apr 20 '14 at 2:55
@Anjesh – That's not exactly a good way to "fix" it; it just happens to work because the text is mostly ASCII. For anything else it'd just end up as garbage. – grawity Apr 20 '14 at 9:51
