Bug in enco-ec.tex and enco-fde.tex

[Uwe Koloska]

Hello,

there are some errors in the files
  tex/context/base/enco-ec.tex
  tex/context/base/enco-fde.tex

I am sorry because this errors are caused by me thinking only half the way.

AFAIK the upper case of (german) szligature is SS and this character is
supposed to be 223 in ec-encoding.  So the proposed changes are:

tex/context/base/enco-ec.tex
	\definecharacter SS 223

tex/context/base/enco-fde.tex
        \installcompoundcharacter "s {\sz}
	\installcompoundcharacter "z {\sz}
	\installcompoundcharacter "Z {\SS}
	\installcompoundcharacter "S {\SS}

>From the "Die amtliche Regelung der deutschen Rechtschreibung" §25 E3:
  Bei Schreibung mit Großbuchstaben schreibt man SS, zum Beispiel:
  Straße -- STRASSE

Stimmt. Die Schreibweise "SZ" ist veraltet bzw. nur bei
Verwechslungsmöglichkeiten opportun.

[True. The sometimes found spelling "SZ" is very old fashioned and only
allowed, if "SS" causes confusion.]

Grüßlis vom Hraban!

\definecharacter sz 255
\definecharacter SS 223

So, \sz remains 255 ?

Shoudl we have a \SZ ?

In t1enc.def (LaTeX) there is:
\DeclareTextSymbol{\SS}{T1}{223}
\DeclareTextSymbol{\ss}{T1}{255}
\ss is the ß letter. It seems that \SS is the uppercase(ß) -> SS letter
(two letters in unicode). It seems that T1 encoding uses a single letter
for SS. We should consider using this one.
The problem is: \SS and \sz are already defined. See below.

"Z should stay SZ!

We have:
  \installcompoundcharacter "s {\SS}
  \installcompoundcharacter "z {\SS}
  \installcompoundcharacter "Z {SZ}
  \installcompoundcharacter "S {SS}

This works perfectly. If T1 encoding has (stupidly?) one character for
SS (two normal captial s; there is non such letter in in UNICODE 3.01 by
the way), we should define something \SZ or is this too confusing.
\SS should produce ß because I don't want to change hundreds of old
documents because of this incompatible unneccessary change.

I think we should produce (as we do currently):
"s -> ß
"z -> ß
"S -> SS  = uppercase "s
"Z -> SZ  = uppercase "z for the rare case that ß becomes SZ as in
MA"ZE vs. MA"SE
MASZE vs. MASSE
Maße  vs. Masse

This is how it is done in LaTeX, isn't it?

We do this using Stra"se and STRA"SE, Ma"se und MA"SE, Ma"ze und MA"ZE,
where's the problem?

I didn't know that it was even used :-) SZ or Eszett is by the way also
a wrong name the ß ligature comes from a long s (unicode 017F LATIN
SMALL LETTER LONG S) plus a normal small s (0073 LATIN SMALL LETTER S),
so the other name "sharp s" (scharfes s) is more apropiate, but
\sz=\SS=ß is the ConTeXt name. Note: \ss is plain TeX and was changed
into \SS because \ss became "sans-serif". Someone (Uwe?) suggested to
name it \sz, so we have (font-ini.tex):

%D \macros
%D   {ss, SS, sz}
%D
%D We are going to redefine \type{\ss} but for those wo still
%D want to have access to the german \SS, we save it's value in
%D \type{\SS}. Ok, I should have used \type{\sf} insead of
%D \type{\ss} in the first place.

\ifx\undefined\SS \let\SS=\ss \fi
\ifx\undefined\sz \let\sz=\ss \fi

Suggest: Leave it as it is, since it seems to be working well!
Or has someone any problems?

I don't know as long as "Z -> SZ and uppercase("z) -> SZ is not
hyphenated we don't need it, do we?
Especially how should it be mapped? \sz is ß which is already very
confusing, \SZ would be SS, and \SS then SZ?
