h is an alias for sanitize_html.

http://api.rubyonrails.org/classes/ActionView/Helpers/SanitizeHelper.html

Try this...

<%= "<b>bold?</b>" %>

vs

<%= h "<b>bold?</b>" %>

That said... the behavior is different in Rails 3... which sanitizes by default. So, in Rails three, try this...

<%= "<b>bold?</b>" %>

vs.

<%= raw "<b>bold?</b>" %>
