/** Some helpers for converting model strings to view strings.
A paragraph string does not have its fields expanded , i . e . , they are
represented by a special character inside the string with an additional
attribute assigned to it . For some tasks ( e . g . , SmartTags ) it is required
to expand the fields to get the string as it appears in the view . Two
helper functions are provided to convert model positions to view positions
and vice versa .
