Springer-Verlag's comments on STIX

Here are the comments from Springer-Verlag on STIX. It took me some time to 
recherche all the information. I hope the comments are helpfull to the STIX
efforts.

Yours,

More characters, needed by Springer-Verlag

a) Mathematical and scientific symbols:

Name		Type	Description
\dsold		B	Dot-Slash-Dot, \textdiscount of LaTeX2e package textcomp
\windschief	B	Straight rising line crossing falling broken line
                        Meaning: skew (of two lines), see e. g. 
                        Dubbel, Taschenbuch fuer den Maschinenbau, 19th 
                        printing, page A-27.
\Slashint	L	Integral with two slashes (Hermite-Integral)
\boxbar		B	Vertical Bar in Box (in TeX's stmaryrd font)
\boxbox		B	Box in Box (in TeX's stmaryrd font)
\oddot		-	Two dots in circle, botanical: bi-annual

b) Geometric shapes

The geometric shapes have no special names (yet).

We distinguish different fill patterns, 

-- dense (usually shown as five lines in a square), this is the one used in 
the UNicode standard

-- sparse (usually shown as three lines in a square)

-- bold (black and white lines are of the same width, usually three 
white and two black lines)

In addition to the shapes already in UNicode, we also use the following 
ones:

Group 1: Squares

Square with sparse upper right to lower left fill
Square with sparse upper left to lower right fill
Square with sparse diagonal crosshatch
Square with bold horizontal fill
Square with bold vertical fill

Square with light gray shading
Square with medium gray shading
Square with dark grey shading

Group 2: Rightangles

Rightangle with upper right to lower left fill
Rightangle with upper left to lower right fill
Rightangle with sparse upper right to lower left fill
Rightangle with sparse upper left to lower right fill
Rightangle with bold upper right to lower left fill
Rightangle with bold upper left to lower right fill
Rightangle with horizontal fill
Rightangle with sparse horizontal fill

Rightangle with light grey shading
Rightangle with medium grey shading
Rightangle with dark grey shading

Group 3: Circles

Circle with horizontal fill
Circle with vertical fill
Circle with diagonal crosshatch

Group 4: Symbols on a horizontal line

Those symbols are placed on a horizontal line such that this line is 
partially covered by the symbol, e. g. diamond on a horizontal line 
looks like the following ASCII graphic: -<>-

Black up-pointing triangle on a horzontal line
Black down-pointing triangle on a horzontal line
Black square on a horizontal line
Square on a horizontal line
Black circle on a horizontal line
Circle on a horizontal line
Black diamond on a horizontal line
Diamond on a horizontal line
Hourglass on a horizontal line
Times on a horizontal line

Some comments:

1) On Alphabetics -- Fraktur

It is not clear wheather &sfr; is a short s or a long s. I propose the 
following solution (the sharp s is in there only for completeness, the 
long s can occur in old style math indentifiers):

sfr	Fraktur short s
longsfr	Fraktur long s
szligfr	Fraktur sharp s

2) On ``not partial differential'' (npart, E390, Table 27)

Can someone give more information on this symbol? It looks like a 
mistake to me. It does indeed occur quite frequently with the meaning
``partial with Dirac slash'', but than a whole latin alphabet A-Za-z
with Dirac slash is needed as well as a small greek epsilon with Dirac 
slash. On the other hand, my feeling is that Dirac slash is treated as a 
diacritical mark within UNicode.

3) On Astronomical symbols

Shall the symbols for the four major asteroids be added?
Ceres
Juno
Pallas
Vesta

4) On Zapf Dingbats

The UNicode standard covers the Zapf Dingbats completely. However, there 
is a strange anomaly: All arrows and arrow-like symbols are 
right-pointing only. This is fine for a postscript font, since 
postscript can rotate and reflect characters. Other technologies (like 
SGML, HTML etc.) cannot. Therefore all mirror images should be added to 
UNicode. A named entity set for the Zapf Dingbats (tentative name: 
ISOZAPFD) is also nice to have.
