[Tikzdevice-bugs] Arial and Other Things

[Charlie Sharpsteen]

Another factor that may be coming into play is font metric caching.  For
example, the string:

"3\\cdot10^{-6}"

Looks the same to the metrics cacher regardless of the font being used- so
you may be getting output typeset in Helvetica that is using cached metrics
that were calculated for Computer Modern.  Try setting:

  options( tikzMetricsDictionary = NULL )

Before loading the tikzDevice and see if it has any effect.
