I do this to control invalid character on my dhcpd.conf (dhcpd version > 4 for ~~):
if not (option host-name ~~ "^[-_0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ]+$") {
log (info, "DEBUG: DDNS name invalid! Not added to DDNS.");
ddns-updates off;
}

~20,000 developers & testers on four continents. . . it or something similar will happen again.
