Upgrade from 1.3.6 to 1.4.0-epa1 looses complete DHCP configuration

Bugs

If I upgrade to 1.4.0-epa1 there’s no DHCP server configured anymore.

show conf commands from 1.3.6:

This appears to be related to the same conditions as this bug I submitted. When a single line fails during the on-boot config-checks, the entire logical section is deleted:
https://vyos.dev/T5991
After a quick check, it is likely this line causing the failure:

l0crian@R86S# set service dhcp-server shared-network-name TEST description 'Gäste' 
  
  Description too long (limit 256 characters)
  Value validation failed
  Set failed

It appears to not like the ‘ä’ character.

I have filed this as a bug report over at ⚓ T6098 Description doesnt seem to allow for non international characters

Feel free to add additional information to the above task when needed.

I’ll change the description and test again.

I can confirm now, it’s the “Umlaut” (ä):

Changed the description to ‘Gaeste’, tried again and everything runs without problems.
