Subject: String index produces unanticipated result

I have the following string I am pulling from a file (asterisks used to
show boundaries of line, and are not actually there:

*    9    3    3    0    0*

I want to test to see if a "9" is in the first five columns of the line.
Typically it is in column five, but not necessarily.

I tried the "puts line.strip[0]" command, which returns "57".  Huh?
Where did "57" come from??  Same thing happens with strip!.

Why isn't this simply removing the leading white space and returning
"9"??  I don't understand how to accomplish my task now.

I tried the online irb, and it gave me "9", like I'd have expected.
