Latest test version breaks update from novelfull.com for me.
I'm using flaresolverr 1.2.9
Trying to update
https://novelfull.com/fey-evolution-merchant.html with the latest test version version resulted in "string argument should contain only ASCII characters" error.
After reverting to the previous release version of FanFicFlare (just switching out the .zip file in the plugins folder, no other changes) update of the same story works again.
