@Zergling_man @kirby Random bytes isn't what's wanted, rather it's random UTF-8 characters.

It can be done on your computer with GNU dd and GNU iconv mind you; `dd if=/dev/urandom of=./random_UTF-8.utf8 bs=1024 count=1 2>/dev/null && iconv -cf 'SHIFT-JIS' -t 'UTF-8' ./random_UTF-8.utf8 && cat ./random_UTF-8.utf8 2> /dev/null`

This isn't exactly completely random, as Shift-JIS does follow some pattern, but it's enough of a mess the output is random enough.
