Input of native language symbols on UNIX/Linux

If you are not able to input native language symbols which differ from the standard Latin letters into a form field, you should check the environment settings. The special symbols are present in German, French, Spanish and other languages which use the Latin alphabet, i.e.: Ñ ñ, Ü ü, Á á, Œ œ, Ô ô, ß.

You can check your environment variables using the following command:

locale

Here are the examples of this command output.
