The script will use the first accent that is available (provided that it is named correctly). That is what I suspected, thanks. The font I was working with had what looked like three different sizes of accent marks and only glyph numbers to tell them apart. That is why I had some 59 empty cells aft...

Just to illustrate how one might access the petite capital version of the German sharp S the way it is created by the UMPC script (SS), I made the section symbol act as the lowercase version of the German sharp s since the lowercase version of the German sharp s was already linked to the German shar...

Finally! Starting fresh after removing all of my little tweaks, the results are much closer to what I expect. With 7838, Germandbls, and 223, germandbls, in place prior to running the UMPC script we get the greatly anticipated SS glyph, germandbls.pcap, alongside the small sharp S, Germandbls.pcap. ...

I experimented on another font which, like mine, contained both upper and lower cases of the German Shsrp S. The UMPC script produced a new glyph, Germandbls.pcap. Trio.png When there was no Capital German Sharp S in the font, the script created a Germandbls.pcap from the germandbls (small German Sh...

Also, @ 50355 of ConpositeData, two s.pcaps are mapped to germandbls.pcap and the SS is, in fact , the uppercase form, not the lowercase.
I advocate for the name "smallsharps" for the lowercase form, "CapitalsharpS" for one form of the capital and "Germandbls" for the other form

You are killing my plans with this in CompositeData: <GlyphMapping>7838</GlyphMapping> <Member id="1"> <GlyphMapping>223</GlyphMapping> <UseMetrics>TRUE</UseMetrics> </Member> </Composite> This is why the lowercase sharp s winds up being used to create the Germandbls.pcap as illustrated in my images...

I am seeing doubles 😎 And, as is usual, my troubles are of my own making, Prior to running Unmapped Latin Petite Capitals.xml, I had created both the Latin small letter sharp s (@codepoint 223) and the Latin Capital letter Sharp S (@codepoint 7838) both of which I take to be replacements for the two...

Nevermind!!!
I discovered the Unmapped Latin Petite Capitals.xml
I see some possible kinks but this should work.
(I would have done the German sharp S a little differently for one thing)

I must be missing something here. The Petite Capitals Private Use.xml script fails to actually create the 155 glyphs I expect it to add to my font. The cells are there with what seems to be the correct code points but they remain empty. I noticed that CompositeData.xml now uses "friendly" names but ...

Not all word processors support all of the OpenType features. Where they are supported, they need to be activated or enabled.
For example, in LibreOffice, the supported features are enabled by specifying feature codes in the font selection box.

Just for jollies, I created a composite glyph in the private use area @ $FB07 with a name of "abform". This glyph was a composite made of the characters "c" and "d". In the OpenType Designer, I added a Standard Ligature 1 feature (liga) and then I added a lookup table Ligature 1 and then I added the...

Congratulations . . . you have crafted a very fine font here.

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.
