I don''t think what you''re looking for is even possible in
general:
you''d need to first parse the entire HTML string, find "15
characters"
and then put the formatting back on. That''s not even including the
possibility of devious stuff like this:

A string with <span style="display:none">hidden
bits</span>.

The first 15 *visible* characters here are "A string with .", but
unless you''re parsing the CSS as well, you''d end up producing
"A
string with h".

Finally, fixed character truncation can be tricky; does the client
*really* want to see "Foo Bar Baz Association" truncated to 15
characters? :)
