There are bugs when using " to get a given name shown underlined.
In case of names like "Ilse" Luise Johanna /Voge/ it happens that
- in the indivdual list there appears the line of first letters like
" | A | B | C | D | E | F | G | H | I | .....
- if you choose the " as the first letter selector no individuals are shown
- it is the same effect in the family list
Example can be examined at
The function to build up the list of first letters needs to consider if the first is a " and to take the 2nd letter into the list in this case.
