Wan dhcp option for ipv6 (string or hexstring ?)

to get my ipv6 i have to send to my isp a vendor class, i made a wireshark capture below :

according to the documentation here : https://openwrt.org/docs/guide-user/network/ipv6/configuration
i should write a string and not a hexstring, so how can i write the non ascii chars at the begining of the string ?

Wireshark is showing an "enterprise id" hexstring before the string "neufbox_NB6VAC-FXC-r0_NB6VAC-MAIN-R4.0.44k_NB6VAC-XDSL-A2pv6F039p".

This doesn't seem to work :

config interface 'wan6'
	option ifname '@wan'
	option device 'eth1'
	option proto 'dhcpv6'
	option vendorclass '0000a00c00416e657566626f785f4e42365641432d4658432d72305f4e42365641432d4d41494e2d52342e302e34346a5f4e42365641432d5844534c2d41327076364630333970'
	option clientid '00030001cc2d1b369ac0'
	option reqopts '12 17 21 22 23 24 25 31 56 64 67 82 83'

Just use Vendor Class. I'm not sure why you identify what you need, but then go on to mention something else. :man_shrugging:

Let us know your results.
