Error building source package ttf-ubuntu-title: Binary change irrepresentable

[Efrain]

Dear all:

I have made some modifications to the ttf-ubuntu-title package (added
new gliphs). I wanted to generate a new source package. obviously the
binary file (.ttf has changed). and the building process fails claiming
that the changes made to that file are irreprensentable which makes
sence.

What is the best way to reflect the changes in this situation?
