>Description:
While I can use /dev/random for tr(1) source (password generation for example) on Linux (CentO@ 5.4 to be precise) and also on gtr(1) from coreutils port, the BSD tr(1) does not want to cooperate with /dev/random output, as below:

FreeBSD% head -c 200 /dev/random | tr -d -c 'A-Za-z0-9'
tr: Illegal byte sequence

FreeBSD% head -c 200 /dev/random| gtr -d -c 'A-Za-z0-9'

CentOS$ head -c 200 /dev/random | tr -d -c 'A-Za-z0-9'

>How-To-Repeat:
FreeBSD% head -c 200 /dev/random | tr -d -c 'A-Za-z0-9'
tr: Illegal byte sequence

FreeBSD% head -c 200 /dev/random| gtr -d -c 'A-Za-z0-9'
x9SMkHI4INJOwwAHhHocHElFdrVJOEMYxgtcVndR

CentOS$ head -c 200 /dev/random | tr -d -c 'A-Za-z0-9'
