Change text version characters

[ghost]

Hello,

It could be interesting to have an option to choose the 0 and 1 characters for the text version.
I would prefer '0' and '1' than ' ' and '*' for example.

Thank you.

I'm not sure it's worth cluttering the options with that, at least on Linux you can just pipe it through "tr ' *' '01'" or similar.
Besides that, is that text output really useful for anything?
