Then again, I doubt anyone in the target audience for this document will be able to decode it by themselves. And if anyone writes them a nice online tool for it; that could be subject to the same censoring that regular clearnet webservers are, on which the file could be saved directly in the first place.
For extra shits and giggles, you can compress the text with a monster compression algorithm like LZMA, then the size will likely be 3-4x less and fittable in the blockchain but nobody would know how to decompress it
