OK, so it's definitely a data change. Can you get the numeric value of 
the character in question, and compare it to the original value
   SELECT ascii(substring(my_column,5,1)) WHERE ...;
   SELECT ascii('6');
You might want an index other than 5 of course.

What I'm wondering is whether this is a single-bit error that has 
occurred. If it is, I'd suspect hardware problems.
