GNUPlot character encoding/locales

[John C. S. <sp...@ly...>]

Hello,

When passing scripts to GNUPlot, I find that it does not understand
things like using 3,1415 instead of 3.1415, so I convert all such
numeric expressions to the 'C' locale style.

This leads me to a more general question: is there a standard for
character encoding of strings in GNUPlot?  Does it depend at all on the
selected locale, or is it always iso-8859-1 or UTF-8 or so?  Does it
depend on the terminal used for output?

Cheers,
John
