Support UTF-8 special characters (like symbols)

[popy2k14]

Current version displays those characters wrong, see:

Here is the source file:
utf-8_symbols.txt

And here the codes used:

Would be nice if SnakeTail can handle those and also display them correctly.

Do not think that will be trivial to draw icons unless there is some magic inside Microsoft ListView
