Re: [Bug-ocrad] GNU Ocrad 0.25 released

Thanks Antonio!

It turns out most of the cases where numbers with underscore weren't picked
up was because of the options I was using (I was trying out the --layout
option, that seems to help in some cases but would break this particular
case.

And I'll try the custom filter.
