Hi
I found a problem with this library.
For numbers 1, 4 and 7 that don't use all spaces,
unwanted characters appear in places where it should be empty.
The library uses char(254) to fill this space.
HD44780s can have one of two different character sets; European or Asian.
If it's the Asia set, it works correctly, if it's the European, the garbage appears.
The solution was to modify the library, putting char(32) instead of char(254).
