Yes, CQL keywords wouldn't need this kind of protection, but the problem here
is for getText when type is Type.STRING. Is it ever used with inputs of that
type? If so and if I'm not mistaken, getText for this CQL string:
{code:java}
'this is a ''quoted'' word'
{code}
would return
{code:java}
'this is a 'quoted' word'
{code}
which is probably an incorrect representation of the CQL string.
