[GreenKeys] Differences in FIGS interpretation

Hi Steve,

I haven't used FLDIGI, so I don't know if there is a setting to change, 
but UC J bell  is a strict ITA2 (EU) version.  UC S is bell in USTTY. 
Several other UC characters get abused as well, for example UC H.

Row 3 of: https://www.navy-radio.com/tty/code-chart-2011.jpg is the more 
common set used by hams in US.

You'll notice there's no % anywhere.  The plus only exists in the WX 
(#1) version.  All that being said, all kinds of exceptions existed 
depending on what the Teletype customer wanted for private line use.
