acts_as_solr vs Illegal character CTRLCHAR code 31

Just found out that 37 is an illegal solr character…
x.gsub(“37″,”) solves the problem…

Patch

# acts_as_solr/instance_methods.rb:62
# remove illegal control character in text  cannot be added ("#{i}" does not work...)
["\032","\033","\034","\035","\036","\037"].each do |char|
  v = v.gsub(char,'')
end
