Re: [squeak-dev] Unicode Ranges you might want to copy

To add to my previous repky, I am curious "how" the letters are written on a morphic display? Is it a bitblt thing? A primitive? A glob of pixels that morphic plops into place?

cheers

Hi Timothy,

I spent several (fruitless) days last year trying to get cuneiform fonts to render properly in Squeak (see here 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.

Hi Folks,

You might find the below handy.

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).

I am also coding a utility class to provide information such as below in a variety of ways.

fwiw, here are my current todo notes for this font information.

unifont

provide link to the unicode spec.

provide browser fonts list.

provide squeak fonts list.

provide phare fonts list ^self squeak fonts list:

what are Variant Selectors ?

show gaps in the ranges.

provide a link(s) to required fonts that will make a range display.

displays on: browser list, squeak, emacs, xterm...

status bar...broken, partial, full.

use cases for fonts

pairs with xyz   example superscripts and subscripts

The goal is to show what works and to find/test fonts that will support stuff.

I am modelling the Seaside app on https://jrgraphix.net/research/unicode_blocks.php

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.
