If you're on Linux, try <code>file -i filename.txt</code>.

<pre><code>$ file -i vol34.tex 
vol34.tex: text/x-tex; charset=us-ascii
</code></pre>

For reference, here is my environment:

<pre><code>$ which file
/usr/bin/file
$ file --version
file-5.09
magic file from /etc/magic:/usr/share/misc/magic
</code></pre>

Some <code>file</code> versions (e.g. file-5.04 on OS X/macOS) have slightly different command-line switches:

<pre><code>$ file -I vol34.tex 
vol34.tex: text/x-tex; charset=us-ascii
$ file --mime vol34.tex
vol34.tex: text/x-tex; charset=us-ascii

You can't reliably detect the encoding from a textfile - what you can do is make an 
educated guess by searching for a non-ascii char and trying to determine if it is a 
unicode combination that makes sens in the languages you are parsing.

There’s no sure-fire way of doing it. At most, you can rule things out. The UTF encodings you’re unlikely to get false positives on, but the 8-bit encodings are tough, especially if you don’t know the starting language. No tool out there currently handles all the common 8-bit encodings from Macs, Windows, Unix, but the selected answer provides an algorithmic approach that should work adequately for a certain subset of encodings.

In a text file there is no header that saves the encoding or so. You can try the linux/unix command <code>find</code> which tries to guess the encoding:

<pre><code>file -i unreadablefile.txt
</code></pre>

or on some systems

<pre><code>file -I unreadablefile.txt
</code></pre>

But that often gives you <code>text/plain; charset=iso-8859-1</code> although the file is unreadable (cryptic glyphs).

This is what I did to find the correct file encoding for an unreadable file and then translate it to utf8 was, after installing <code>iconv</code>. First I tried all encodings, displaying (<code>grep</code>) a line that contained the word www. (a website address):

<pre><code>for ENCODING in $(iconv -l); do echo -n "$ENCODING "; iconv -f $ENCODING -t utf-8 unreadablefile.txt 2&gt;/dev/null| grep 'www'; done | less
</code></pre>

This last commandline shows the the tested file encoding and then the translated/transcoded line.

There were some lines which showed readable and consistent (one language at a time) results. I tried manually some of them, for example:

<pre><code>ENCODING=WINDOWS-936; iconv -f $ENCODING -t utf-8 unreadablefile.txt -o test_with_${ENCODING}.txt
</code></pre>

In my case it was a chinese windows encoding, which is now readable (if you know chinese).

<blockquote>

</blockquote>
This question is 10 years old as I write this, and the answer is still, &quot;No&quot; - at least not reliably. There's not been much improvement unfortunately. My recent experience suggests the <code>file -I</code> command is very much &quot;<a href="https://www.thefreedictionary.com/hit-or-miss" rel="nofollow noreferrer">hit-or-miss</a>&quot;. For example, when checking a text file on macOS 10.15.6:
<pre><code>% file -i somefile.asc
somefile.asc: application/octet-stream; charset=binary
</code></pre>
<code>somefile.asc</code> was a text file. All charcters in it were encoded in UTF-16 Little Endian. How did I know this? I used <code>BBedit</code> - a competent text editor. Determining the encoding used in a file is certainly a tough problem, but...?

I have <code>.txt</code> and <code>.java</code> files and I don't know how to determine the encoding table of the files (Unicode, UTF-8, ISO-8525, …). Does there exist any program to determine the file encoding or to see the encoding?
