* FIX: bots could generate errors when slug generation method is encoded
When slug generation method is encoded (non default) then bots could
cause errors in the logs for urls containing special chars.
ó for example in a URL can be requested in a valid ASCII-8BIT string, and
later when joined to UTF-8 would result in encoding issues.
Fix here ensures we force encoding correctly for outlier cases.
Browser tend to always encode these chars, hence we did not notice this.
