Override labels for all inputs?

[molfar]

How can I override label_text for all inputs globally for all inputs? I need to set there some special sign (prefix) there, similar to (optional or required).

formtastic/lib/formtastic/inputs/base/labelling.rb

Lines 19 to 21 in 69a01f0

	def label_text
	((localized_label || humanized_method_name) + requirement_text).html_safe
	end
