 Illegal byte sequence

 /dev/random just isn't guaranteed to produce correct multibyte characters
 (and I guess you are using multibyte locale). Try setting LC_CTYPE to
 single byte locale:
 > locale
 LANG=en_US.UTF-8
 LC_CTYPE="en_US.UTF-8"
 LC_COLLATE="en_US.UTF-8"
 LC_TIME="en_US.UTF-8"
 LC_NUMERIC="en_US.UTF-8"
 LC_MONETARY="en_US.UTF-8"
 LC_MESSAGES="en_US.UTF-8"
 LC_ALL=
 > head -c 200 /dev/urandom | tr -c -d 'A-Za-z0-9'
 tr: Illegal byte sequence
 > head -c 200 /dev/urandom | env LC_CTYPE=C tr -c -d 'A-Za-z0-9'
