<p>Hi Timothy,</p>
<p><br>
</p>
<p>do you also know Unicode class and, in particular, its class variables and its testing selectors? Not sure whether this is on the same abstraction level as your work - just wanted to add this pointer.</p>
<p><br>
</p>
<p>Also note that Unicode class's character classification does not yet support UTF-16 characters - I have added this to my todo-list some disgracefully long time ago [1] and not yet managed to return back to this issue (so sorry, Levente!).</p>
<p><br>
</p>
<p>Best,</p>
<p>Christoph</p>

<div style="font-size:10pt;font-family:Verdana,Arial,Helvetica,sans-serif;">Hi Eric<br>
<br>
<br>
Thanks for the heads up!<br>
<br>
Doing some lite browsing on the matter, I found these resources....<br>
<br>
https://unicode-table.com/en/#control-character<br>
https://css-tricks.com/almanac/properties/u/unicode-range/<br>
http://www.alanwood.net/unicode/alphabetic_presentation_forms.html<br>
<br>
<br>
<br>
That last one looks very useful and I will ve working through it.<br>
<br>
The middle one claims that fonts can be loaded dynamically when needed.<br>
<br>
An intersting thing is that the alan wood site displays the $ sign under the currency range, but the jgraphix website does not!<br>
<br>
<br>
It is also somewhat apparent that "like" ranges are not contigous.<br>
<br>
Thanjs again for your gelp!<br>
<br>
Cheers, <br>

<div>Hi Timothy,</div>
<div><br>
</div>
<div>I spent several (fruitless) days last year trying to get cuneiform fonts to render properly in Squeak (see
<a href="https://www.hethport.uni-wuerzburg.de/cuneifont/" target="_blank">here</a> for examples of the fonts). There does seem to be an issue with rendering glyphs above a certain code point from what I recall. I am definitely interested in your work and what
you end up finding out.<br>

<div>Hi Folks,<br>
</div>
<div><br>
</div>
<div>You might find the below handy.<br>
</div>
<div><br>
</div>
<div>Fwiw, I have coded the UnicodeRangeBrowser SeasideApp to display all the below (it times out before all display, I will be doing refactor and more development).<br>
</div>
<div><br>
</div>
<div>I am also coding a utility class to provide information such as below in a variety of ways.<br>
</div>
<div><br>
</div>
<div>fwiw, here are my current todo notes for this font information.<br>
</div>

<br>
</div>
<div>The goal is to show what works and to find/test fonts that will support stuff.<br>
</div>
<div>I am modelling the Seaside app on <a href="https://jrgraphix.net/research/unicode_blocks.php" target="_blank">https://jrgraphix.net/research/unicode_blocks.php</a> <br>
</div>
<div>But...for each unicode range, I intend to display smalltalk specific helpers on what/where to get fonts for both the browser side and the image side.<br>
