I would like to have a B91 system where each 52b maps to exactly 4 char in base91. Is it possible?
2^13 in base91 is 90:2, that means everything from C" (90:2) to "" (90:90) should be invalid pairs.

I though Base91 will sometimes put 14bits into 2 characters due to "higher compression", and i wanted a version of base91 that WILL NOT switch between 13bit and 14bit blocks.

lines 259 & 260

while( out.size() && out.back() == '\0' ) out.pop_back();
               if( out.size() && out.back() == '\1' ) out.pop_back();

are C++03 incompatible, so change them to smth like this

 while( out.size() && *(out.end()-1) == '\0' ) out.resize(out.size()-1);
               if( out.size() && *(out.end()-1) == '\1' ) out.resize(out.size()-1);
