Hi Dick and all,
Just to correct a slip, it's Bryan here
I do confirm your findings with Paket6.2 it simply loses
the character 253 when it scrolls off the screen. It's
happy scrolling up and down in the normal text area
but as soon as the text goes off the screen top or bottom
the little 2 disappears. I suspect its a bit late in the
day to make a bug report now :-)
As to what I sent, you and Pete G6KUI are correct it was
character 178 so the problem is not with you.
Andy GM7HUD describes the situation well and gives good advice
about sticking to codes below 128 as far as is possible
to ensure most people can read what you sent and Pete G6KUI says
I should get some proper packet software :-)
I'm actually using some currently developing software called
Dialog by 40tude that is attempting to provide support for
worldwide compatible communications but as Andy indicates it's
not an easy task. I did enter the character with ALT 253 and
it both displayed the correct superscript 2 character as I
typed it and when it displayed the bulletin after it was
re-downloaded with NNTP from the amprnet but it was obviously
character 178 when viewed in normal ax25 packetland.
As this software is trying to provide a newsreader that
can be used in all manner of languages it is very
versatile and therefore a pig to set up fully even if I did
understand the implications of unicode and different code
pages, which I don't. It has some useful features
in that it can hot switch codepages and set default ones
for each newsgroup so that I can set a suitable codepage
for ampr.rec.tech to display G8MNY's ASCII drawings
without affecting the display of other newsgroups.
I think it currently chooses its own character set for a best
match from what you type in so when I've got a few weeks
to spare I'll see if can be forced into submission!
My main reason for choosing it is that is the only FREE
newsreader I've found that allows me to edit my own X-headers
to allow me to gate back into AX25 and maintain the randomly
generated 'TO' fields.
It's not all bad news regarding my character 178 as while
I'm at work I often use the web interface at GB7PZT to
view bulletins rendered in HTML and have always accepted
that IE6 on the works desktop will not display John's ASCII
circuit diagrams correctly but I was interested to note
that my character 178 was the only one that displayed
the superscript 2 correctly using that combination :-)
