The Joomla .ini files require to be saved as UTF-8.

After editing I'm not sure if the files are UTF-8 or not.

Is there a Linux command like file or a few commands that would tell if a file is indeed UTF-8 or not?

    You cannot tell the encoding of a file. You can only make a smart guess. You might mostly guess right, but sometimes guesses fail. file is an example of a program doing smart guesses. – Marco Sep 24 '13 at 21:17

    @Marco: It is possible to verify whether it is valid UTF-8 or not, however. There are some encodings which can mistakenly pass as valid UTF-8, but it almost never happens with ISO-8859-𝒏 or Windows-125𝒏 encodings/charsets. – grawity Sep 24 '13 at 21:40

You can determine the file encoding with the following command:

file -bi filename
  • This answer should be accepted. The explanation for the -bi options is in the man file. – Jérôme Jan 13 '16 at 14:04
  • is it supposed to work on macos as well ? I get regular file on a file I though was utf8 – nicolas Apr 24 '16 at 15:49

    @nicolas For MacOS you could try file -I filename (-I is a capital i). – Rik Apr 24 '16 at 16:07
  • @Rik I can confirm – nicolas Apr 24 '16 at 16:08

    Does this read the whole file? – ctrl-alt-delor Mar 30 '18 at 15:17

There is, use the isutf8 command from the moreutils package.

  • @davidpostill I'm curious, is bad practice to cite the author in the reference? – Pablo Olmos de Aguilera C. Aug 28 '16 at 20:26
  • No. However, it is good practice to make the link say where it leads me. Assume I'm reading only the blue text. After the edit, I can tell why and when I should click that. Before, I could not. (It wasn't me who made the edit but I'm like 94% sure that this is what it was about.) – Hermann Döppes Dec 31 '18 at 0:00
  • Nice, and works nicely with find -type f -exec isutf8 {} +, because it also quotes the filename. (And with using find ... -exec ... + is also fast) – Tomasz Gandor Mar 22 at 13:28
