Somewhere I once saw a question regarding how to insert extra white ( ) spaces between words. There are even add-ons for it.
However, in MS Windows, I found a very easy way to insert a hard white space ( ) code into a Wiki document with very little work. Whether or not it works on other than Windows operating systems, I cannot say.
You can very easily put any number of extra white spaces between words this way.
1 ... Move the editing cursor to where you want to insert the extra white ( ) space.
2 ... Hold down ALT key and type the digits 0160 and a white ( ) space will be inserted at that location.
Do this for every white space you want to insert in your Wiki document.
