Hi Jiri,
Yes, that's the same problem. Put also a dummy index, it should work
the same way. In ROOT the character positioning is done using the TrueType
font engine on the screen and on PS. It works well but my guess is that
the the PS fonts sizes and the TrueType fonts sizes are a bit different.
As you put a index at the end of a long character string the cumulated
error begin to be visible. Putting a dummy index, as I suggested in my
previous email, cuts the long string and the index is then linked to "x"
only and not anymore to the long string. I'll see if I can fix that
systematic error.
Cheers,
Olivier
