Firewall rules separator character support
I was playing around with the really neat firewall rule separators that were introduced in pfSense 2.3. I noticed that some of my separators kept disappearing after pressing Save. It seems like a separator text containing any character within the extended ASCII code 128-255 is removed upon saving the rule set.
In my case, I had words containing "åäö" from the Swedish alphabet that kept disappearing. I had a hypothesis that it may only accept 7-bit ASCII, but that could be disproved by adding a rule with the text 日本語, which was left untouched upon saving. Could there be a bug in the validation?
