In a message on 02-21-19 Maurice Kinal said to Holger Granholm:

Hi Maurice,

 HG> However, if diaeresis is the same as the 'divide' sign

OK, the divide sign on the numerical keypad is a dash with dots above
and below the dash.

MK> It is the 'o' character with two dots on top.  The 'o' character

OK that's the umlaut 'o' that exists in swedish, finnish and german
languages.

MK> with the 'divide' sign - I call it the slashed 'o' which hardcore
MK> encoding gurus call 'LATIN SMALL LETTER O WITH STROKE' - ....

That's the letter in danish that represents the umlaut 'o' in swedish,
finnish and german.

 HG> In Latin 1 it's represented by chr code D8

Yep, that represents the capital umlaut 'O' of swedish, finnish and
german.

MK> That is 'LATIN CAPITAL LETTER O WITH STROKE' and also doesn't exist
MK> in CP437.

 HG> In Latin 1 it's represented by chr code D8 or dec.216 which
 HG> happens to be the same as in CP 437.

MK> No it isn't.  According to
MK> https://en.wikipedia.org/wiki/Code_page_437 D8 or dec.216 is a line
MK> drawing character and in latin1 it is 'LATIN CAPITAL LETTER O WITH
MK> STROKE' or character 'Ø' in utf8.

Right. Thanks for that 'Ø' addition to my UTF conversion table.

 HG> "IBM OS/2 Warp 4" "Keyboards and Code Pages"

MK> I found a pdf online entitled "OS/2 Warp Server for e-business,
MK> Keyboards and Codepages" and do not see PC8 listed in there.

In my vocabulary PC8 is what is called ASCII 2 or extended ASCII and in
IBM's code pages 850. This CP 850 is also called 'Multilingual'.

MK> It does have 'Codepage 437' and 'Codepage 819 - ISO 8859-1' and
MK> comparing them shows the same results I have stated above.

 HG> MK> '...' En Møøse hade en gång min syster ...
 HG> What is this .................^^ in Latin 1?

MK> F8 or dec.248 (not a character in CP437). Yes it is and represents
the degree sign in code pages 437, 850 and in 819 as B0 dec.176.

When I want to insert the degree sign in a Windows DOC I use ALT+0176.
However, I haven't found that sign in Messenger.

MK> ..... the second and third characters in Møøse,
MK> and E5 or dec.229 (86 or dec.134 in CP437) for the second character
MK> in gång.
MK> "LATIN SMALL LETTER A WITH RING ABOVE" which I believe in Swedish is
MK> called the small letter angstrom.  Please correct me if I am wrong.

Correct, but so far I can't recall having seen that letter in a danish
text, but I may be wrong. Let's hear what Benny says <BG>.


Have a good night,

Holger
