randomize any file (unicode or otherwise) with a byte-sized alphabet
Do a make in the directory.
As long as the total number of unique characters you use is less than 256 (any utf8 unicode character counts as one character), you can use the program to encode a file. The fewer unique characters you use, the more the encoded file will look like a random binary file.
Run ./encod main.cc to create a main.cc-decoder and main.cc-encoded file.
You can then run the program in decode mode by running
./encod -d main.cc-decoder main.cc-encoded, which will create the file
main.cc-encoded-decoded which should be the same as the original main.cc file.
You can then use the program ent to see how random the file is:
ent main.cc-encoded will give some output. (Install on Debian/Ubuntu
via apt-get install ent.)
All the files besides utf8.cc/h are under the AGPL v3 license (in LICENSE),
and utf8.cc/h are distributed with the license found in their headers. They
