can't really comment much on the DC topic itself,

i think NULL terminated UTF-8 encoded strings is the right thing to do
when it comes to down to "serial numbers", because they are not
numbers but codes - in theory with non-iterative parts of any possible
language and encoding.

i've grown up seeing products with pretty long serial numbers with non
ASCII characters (wait until the russians get a peace of the DC
market) and i'm pretty sure some of those will not fit in an uint32_t.

now, of course, all text is also numbers, but still...
