Font Forum

Your project seems odd to me on the surface. As Ewrin suggested, searching for "contextual substitutions" migh give you some ideas . . . https://forum.high-logic.com/search.php?keywords=contextual+substitutions&terms=all&author=&fid%5B%5D=3&sc=1&sf=all&sr=topics&sk=t&sd=d&st=0&ch=300&t=0&submit=Sear...

Nice tutorial, Bhikkhu.

Bhikkhu, that script font in your illustration above is gorgeous! Is it one of your creations?

Cool! I learned something today

Animated PNG files . . . Watch the shift states on the left for the different keyboards.

Just to illustrate mapping a calculator font to a US keyboard shown in kbd01. kbd01.png I created six keys (Sin, Cos, Tan, Sin-1, Cos-1, Tan-1) and mapped them such that the right Alt key gives you the three shown in kbd02 kbd02.png Using shift with the right Alt key gives you the inverse functions ...

As Erwin has suggested, Microsoft keyboard layout creator offers the ability to create a keyboard such as "English (United States) United States-International Keyboard" where a large collection of accented Latin characters have been mapped to standard keyboards and seems to have a large number of op...

Unless you are into it for the fun of it, why re-invent the wheel?
There are some free calculator key fonts on the web.
One example: https://education.ti.com/en/software/de ... 557992/83p
There are also fonts which emulate various calculator displays as well.

After looking at several examples of Small and Capital Sharp S in other fonts, I suppose that FontCreator's rendition could be either small or capital … whichever you think it is, the other one needs to be created in CompositeData.xml.

I am a little confused about the Latin Small Letter Sharp s (U+00DF) and the Latin Capital Letter Sharp S (U+1E9E). The Latin small letter sharp s generated by complete composites resembles the uppercase small sharp S and it has the height of a capital letter. 223-02revised.png Mapped at 223, the fi...

I misspoke, the SS and the Ŋ do have small caps code points so they can stay, I guess

I am going over the PCPU script in detail to see that it conforms to the small/petite capital code points in the CompositeData.xml. Apparently, code points were established for various non-letter characters,!$%&()?[]¡£¥¿, I suppose to be re-sized to match the small caps. In the original PCPU script,...

Well, I tried it out ... I changed that UnicodeData.txt entry to:
E9DD; PETITE CAPS LATIN CAPITAL LETTER E WITH TILDE;Ll;0;L;;;;;N;;;;;
and when I ran the PCPU script, all of the accents were down to just above the x-height as they should be.
Yahooo!

In examining the various locations where Ẽ and ẽ are "defined", I found that in the UnicodeData.txt file, the entry for Ẽ as a petite capital seems to identify Ẽ as uppercase whereas the adjacent petite capital entries mark them as lowercase: E9A5; PETITE CAPS W DIAERESIS;Ll;0;L;;;;;N;;;;; E9BD; TIT...

Bhikkhu said: Why do you need support for Ẽ and ẽ. These are included in Latin Extended Additional, to complete the character set and support Vietnamese, etc. That seems to be a strange question coming from a typography maven!!! Ẽ, ẽ is a letter in which the tilde indicates a nasal vowel. It is the ...

Ok, one little step closer . . . The problematic Ẽ must be added to UnicodeData.txt in TWO places. As it stands now, UnicodeData.txt is incomplete ... at least in the area of the Petite Caps. Blocks.txt also needs extensive revision in order to properly display the PUA ranges. The only sources I hav...
