Ärende: Character codes
=======================
Hey Holger!

Note that I am replying on a different machine this time since I am in the
middle of a major overhaul on the raspi3b+ which will take at least another 32
hours.  The Swedish, Danish, and Spanish MøøSGing configurations are on that
machine.  This machine is the English jobber.  I also have a Dutch jobber on a
totally different machine - also a x86_64-pc-linux-gnu host - but I decided to
reply on this one instead.

 MK>> That translates to the '÷' character in utf8 - usually written
 MK>> as U+00F7 or \u00f7 in bash.

 HG> This is also a new sign for my UTF conversion whatever use I may
 HG> have.

An excellent online source for utf8 characters is http://www.utf8-chartable.de/
as they give the 8 bit codes that show up in hex editors to the corresponding
utf8 characters.  For example U+00F7 will show up as a hex 'c3 b7' pair whereas
the small slashed 'o' characters in Møøse show up as 'c3 b8' hex pairs.  So
in bash speak this should produce the utf8 division sign;

-={ '<Esc>:read !echo -e "\u00f7 \xc3\xb7"' starts }=-
÷ ÷
-={ '<Esc>:read !echo -e "\u00f7 \xc3\xb7"' ends }=-

Imagine that!!!  It works!!!

Offhand I am thinking it might make the basis for converting utf8 to whatever 8
bit codepage you are using by just replacing 'c3 b8' combinations with a single
hex character that represents the divide sign in your codepage of choice.  So
for CP850 a conversion vector would look something like this;
's/\xc3\xb7/\xf6/g' which will replace ALL U+00F7 characters with a single f6
character.  For the Møøse that would be 's/\xc3\xb8/\x9b/g' and then everyone
will be happy including the Germans.  ;-)

 HG> If I translate that german line to swedish, norwegian or danish

Yes that can definetly screw things up.  I've done it from english to whatever
and then from whatever back to english and gotten strange results.  Let's try
it here;

-={ '<Esc>:read !trans -b -no-ansi -s english -t swedish "A Møøse once bit my
sister ..."' starts }=-
En möse hade en gång min syster ...
-={ '<Esc>:read !trans -b -no-ansi -s english -t swedish "A Møøse once bit my
sister ..."' ends }=-

We're already off to a bad start but let's leave the möse alone for now;

-={ '<Esc>:read !trans -b -no-ansi -s swedish -t english "En möse hade en
gång min syster ..."' starts }=-
A muzzle once had my sister ...
-={ '<Esc>:read !trans -b -no-ansi -s swedish -t english "En möse hade en
gång min syster ..."' ends }=-

That didn't work out so well but what about this?;

-={ '<Esc>:read !trans -b -no-ansi -s swedish -t english "En Møøse hade en
gång min syster ..."' starts }=-
A mousse once had my sister ...
-={ '<Esc>:read !trans -b -no-ansi -s swedish -t english "En Møøse hade en
gång min syster ..."' ends }=-

Not much better is it?  Oh well ... despite this I am sticking with the
Møøse.  If you have a better Swedish translation I would like to see it but
the Møøse stays, no matter what my sister or anyone else has to say about it.

Life is good,
Maurice
