Well I can see your problem now. The difference from what I did and
what you did (and this is a guess), is that I created my test cells
with the less than as an Input cell and then changed the style to
Text. So I created another test case with the cell being created as a
Text cell initially, and sure enough it shows the problem.

So two workarounds are available:

1. Create your cells as Input and convert them to Text with the Format/
Style/Text command
2. Use another type of less than, e.g. \LessSlantEqual which does not
seem to have the same problem.

Wolfram, you have a bug - IMHO. Because the problem does not occur in
both types of Cells (Input and Text), I sure would guess the problem
is Mathematica's and not a PDF/Adobe problem.
