Liberation Sans does have a square symbol, along with many other symbols.
To get the square:
* double-click the text and place the cursor where you want the square to be inserted;
* choose menu "Insert -> Glyph";
* press the "Show/Hide Enhanced Palette" button (looks like a table);
* in the "Character Class" drop-down (top-right) choose "Geometric Shapes";
* double-click the square glyph;
* press the Insert button;
* close the "Enhanced Character Palette" dialog;
* close the "Character Palette" dialog.
For other symbols just choose a different character class and double-click on the symbol you need.
As for the space between the text and the symbol, that really depends on exactly what you want but an "en space" or "em space" is usually fine - "Insert -> Spaces & Breaks -> Em (or En) Space". You shouldn't normally need anything more than that - the quoted article describes it well.
