+There has been a report of a bug which I have not been able to reproduce and
+which the original reporter has not yet gotten back to me with the results of
+a test, so I have opted for an alternate approach which does not preclude the

+TeX Gyre Pagella font and sets this as the default standard font for all web
+views.
