def self.allValuesAreStrings(hash)
  hash.each do |_, value|
    if !(value.is_a? String) then
      return false
    end
  end

  return true
end

.fixEncoding(v) ⇒ Object

Rack apparently uses 8-bit ASCII for everything, even when the string is not 8-bit ASCII. This reinterprets 8-bit ASCII strings as UTF-8.

If we are unable to do this reinterpretation, return the string unchanged, but log a warning that points to the caller.

    return forced
  end

  Rails.logger.warn "[#{caller_locations(1, 1)}] Unable to fix encoding: not a valid UTF-8 string. This will likely cause JSON serialization to fail."
  v
end

.hashToList(hash) ⇒ Object

Converts a Hash into a list of Hash objects. Each entry in the given Hash will be represented in the output by a Hash object that maps ‘name’ to the entry’s key and ‘value’ to the entry’s value.
