Linux file configuration

Test: w ##class(%File).Exists("/path/to/файл.txt") should return 0 if file does not exist and contains non-latin characters.
If presence of non-latin character in a filename causes %File:Exists to always return 1, set System call I/O table to UTF8. To do that, execute in a terminal:

%SYS>d ^NLS

We need to register dav protocol with firefox. To do that:

Type about:config into the Location Bar (address bar) and press Enter.
Right-click -> New -> Boolean -> Name: network.protocol-handler.expose.dav -> Value -> false
Next time you click a link of protocol-type foo you will be asked which application to open it with. Choose LibreOffice: /usr/bin/loffice
