        tree-wide: spelling fixes

The commit in question changed a binary file. I didn't look at the diff in
particular, so I have no idea what exactly was changed. However, the file
is generated and it looked highly suspiciuous. Therefore, I reverted that
part.

Note that this is generated by "make update-unifont" so really no reason
to touch at all.
