Cropping text strings

Hello,

This statement here can return a very long paragraph
<%=h openjob.ProblemDesc %>

Is there a way to trim it to say the first 50 characters? In VBScript
I would use Left(). (I am working in ruby on rails if that matters)

As will the following:

openjob.ProblemDesc.first(50)

Hate to be anal, but that would return the first 50 *bytes*, not characters.

Cool. Here are two other ones:

openjob.ProblemDesc[ 0, 50]
openjob.ProblemDesc[ /.{50}/u]
