"The RNDF is a tab-delimited ASCII file. Within the RNDF, strings have a maximum length of
128 characters, and do not contain any spaces, backslashes, or *. Integers are always positive
and have a maximum value of 32,768."
Right now, there are some strings which are being generated with spaces. I would add the length constraint too.
From the Darpa Chanllenge spec:

The samples at Darpa web page (https://www.grandchallenge.org/grandchallenge/resources.html) show the strings with '_' characters instead of blanks. I suggest doing the same.
