Subject: Weird error using String#[]

Please check out the attached file. I am writing a script to notify me
when a few select items become available. It hits a web page then parses
the information in order to determine whether the item is available or
not.

When I parse the values out I start seeing some really weird results
when calling the String#[]. What is even weirder is that when I put
these results with something like puts "val: #{weird_val}" it also
replaces part of the string being put, "val: ".

Example:

ret = res[spos, 90]
puts "ret: #{ret}"
# ^^^^^
# Expected live result (works in baseline):
# ret: id="ProdAvailability"><span style="font-weight: bold; color:
# #000;">Availability:</span>Ou
#
# Actual live result (missing Ou on end, r in pos 0 replaced with O):
# Oet: id="ProdAvailability"><span style="font-weight: bold; color:
# #000;">Availability:</span>

If I pull the contents from the web site, it doesn't work. If I pull the
contents from a string saved in the script (denoted as baseline in the
file), it works fine.

I have been spinning my wheels for 2 days now and am pretty sure that I
am overlooking something obvious.

Anyone have any idea what is causing this?
