I come across the same problem. and my solution is to use hex instead
of normal string.
man ifconfig, you will see:
ssid ssid
Set the desired Service Set Identifier (aka network name). The
SSID is a string up to 32 characters in length and may be speci-
fied as either a normal string or in hexadecimal when preceded by
`0x'. Additionally, the SSID may be cleared by setting it to
`-'.
If you add the following line to /etc/rc.conf, It will works.
ifconfig_ath0 = "DHCP ssid 0x6d79206e6574776f726b"
Hope it helps.
