Scott, thanks for the Unicode chess piece pointers!
In a 2009 posting Martin helped me to get the .gif pieces correctly placed
from a stylesheet (quirks mode):
www.biglist.com/lists/lists.mulberrytech.com/xsl-list/archives/200907/msg00180.html
I just took the stylesheet for displaying a chess position and modifyed it
to use "your" unicode characters instead of .gifs.
You may see the result here:
http://stamm-wilbrandt.de/en/xsl-list/chess/bw/p2n.xml
It uses a (modified) stylesheet:
http://stamm-wilbrandt.de/en/xsl-list/chess/bw/boardAN.xsl
The previous board view can be seen here:
http://stamm-wilbrandt.de/en/xsl-list/chess/p2n.xml
Under Linux the new view looks perfect.
But I tried on a Windows 2003 server as well on a Windows XP machine, and
these unicode characters all get displayed as empty rectangles :-(
So the advantage of the .gif approach is a guaranteed outcome ...
I have two questions.
1)
While the chess pieces are fine, I was not able to find charcter(s) for
the empty fields -- the characters chosen above are at least from the
right size, but look not really "empty" (rectangles).
Which Unicode character will fit the size of the chess pieces and be either
complete white or complete black?
2)
With style="font-size: 64" the following chess pieces get really big:
http://stamm-wilbrandt.de/en/xsl-list/chess/bw/bw.html
What needs to be changed in boardAN.xsl to resize the chess pieces there?
I tried at least 5 different options and none worked.
Is this another problem with quirks mode?

Nice work. I don't have any node-set() suggestions, just a comment about
the chessboard representation. You don't need to use images at all here.
Unicode actually contains all the characters for chess pieces, at
codepoints 2654-265F (9812-9823). White queen is 2655 (9813) and black
queen is 265B (9819). Could simplify your code a little.

Subject: [xsl] XSLT 1.0 n-queens and questions
Hello,
I posted a XSLT 1.0 implementation for n-queens running in all big5
browsers
https://www.ibm.com/developerworks/mydeveloperworks/blogs/HermannSW/entry/n_queens_xsl_xml14
It produces all solutions for 4<=n<=9, nicely grouped.
I have two questions on the solution:
1)
Grouping is done by two solutions considered equivalent if one can be
transformed into the other by rotations and/or mirroring.
I did not find a way to make this "equivalence" available in xsl:key for
using Muenchian grouping -- can anybody think of how Muenchian grouping be
used instead the "handmade" duplicate elimination in n-queens.xsl.xml?
2)
I made much use of exslt:node-set() function although the templates itself
use xsl:call-template and xsl:apply-templates.
Is a more "functional" solution without so many exslt:node-set() calls
possible in XSLT 1.0?
