[PHigby]

I create linguistic epubs for a non-profit. Currently we have an ePub that the author is requesting his book to be in Gentium font and to display the "opentail" g [a circle with a tail that points left or 'single-storey'] over the "looptail" [two circles, connected by a line on the left side or 'double-storey'].

I created a test epub and font in normal or bold I get the looptail g, but in the italic form the opentail g is displayed.

This also effects the a [double-storey a and single-storey ɑ], likewise.

Is there any way to set the display for the reader?
