<div class="moz-cite-prefix">I have TeXworks 0.4.6, r.c. 29723a,

MikTeX. MikTeX was updated last week so everything should be
current. When you say "as I controlled in XeLaTeX," I take that
to mean you tried some Plane 1 characters and they worked
correctly -- is that right? I have not seen a reply from Philip.<br>

It could be a problem of your installation of the TeX
distribution or your TeXworks installation.<br>
<br>
By the way, which distribution you are using and which TeXworks?<br>

a Windows issue, though, since the characters in question work
correctly in several other Windows programs (Word, Libreoffice,
Notepad) -- that's why I think it's a TeXworks issue. The
characters are in the Old Italic block of Unicode, U+10300 and
higher. <br>
<br>
Could TeXworks have an issue with characters in the
supplementary planes? I don't normally use any of these scripts
except Old Italic. To test this, I just copied some characters
from the Runic block and pasted them into Notepad -- OK. Then I
pasted them into TeXworks and changed the font to one that I
know supports Runic. This time I got black rectangles. (This
was a different font from the one that I used with Old Italic.)
Furthermore, the .notdef glyph in this font has the shape of a
tall narrow rectange, but I am seeing almost squares. There
does seem to be something going on here. <br>

rectangles <br>
<br>
<br>
The rectangles are "notdef" characters. They appear when Windows
detects what it considers asa “not defined” character. You may
have a problem with default ignorable code points. <br>
This comes about because of the concept of"default ignorable
code points". Windows has incorporated andprogressively enhanced
its Unicode support since Windows 2000. Where in thepast legacy
applications running in legacy versions of Windows took
charactersfrom the range 128-159 and displayed them, it appears
that Windows will nowintercept calls for characters in hacked
(customised) fonts and display (ornot!) one of the three
variants stipulated for this scenario:· a zero width character
(the screen is blankwhere a glyph should appear, and characters
either side of the glyph appear tobe adjacent)· a space (i.e.
decimal 32) – blank space on thescreen again.· the rectangle
Microsoft refers to internally as'notdef' <br>
These are "defaultignorable code points". Copy the "blank
spaces" or the rectangles - whichever - and paste into MS Word.
Then check each character position in turn using the Alt-X trick
to reveal the intended code point value. <br>
Contact me off-list if you wish. <br>

1. Re: Plane 1 characters not visible in TeXworks (David J.
Perry) <br>
This is a followup to my post from yesterday. Things get
weirder. <br>
<br>
Earlier tonight I opened TexWorks to do some more work on the
file I <br>
used yesterday. This time I saw empty rectangles where the Old
Italic <br>
characters are. This is better than nothing, although I'm still
not <br>
sure why the characters won't display. <br>
<br>
A few minutes ago I wanted to make a last-minute correction and
opened <br>
the file again. Same computer, same fonts, same everything as
earlier <br>
today, but now we are back to total blanks. ??? <br>
<br>
