c2sc failed to affect uppercase letters already modified by locl, but only for some languages.

Issue: Hungarian-adapted diacritics enabled by ss13 didn’t match well between upper and lower case.

This sample uses combining diacritics. It should identical to the sample above.

Proposal (A): Use lower-case diacritics over upper-case letters. This would look boldly striking, but create vertical overhang. However, this may not pose a problem, considering that stylistic sets are only supported by professional software and are always off by default. (This sample attempts to fake the desited look by adding combining diacritics to Cyrillic base letters А/а, Е/е, І and О/о. Note that Ú/ú, Ű/ú and í cannot be thus faked, since no matching Cyrillic letters exist.

Proposal (B): Use smaller upper-case diacritics over lower-case letters. (No problems with fonts metrics.)

IJ and ij can now be created with »dlig« plus »nl«.

With »ss02«, ß and a (incl. all derived letters with diacritics) had the wrong Unicase and SC glyphs.

Most ſ-ligatures only worked when »calt« was disabled.

ꜩ can now be created with »hlig« in regular and italic fonts, but is appropriately suppressed in Unicase and SC fonts.

»lnum« and »tnum« now can be combined to achieve tabular lining numbers.
All number sets now have optional “dotted zeroes.”

Dotted zeroes were too short in Infant and SC fonts.
Dotted zeroes were missing in Upright with »tnum« and »onum+tnum«.
Currency signs were too short in Regular Italic with »tnum« (but not »lnum+tnum«, although both settings should probably behave the same), Upright with »lnum« and in Infant Italic.
The dotted zero’s dot was too low in Infant Italic with »onum«.
The dotted zero’s dot was too low with »onum+tnum« in both Infant Regular and Infant Italic.
Currency signs were too short in all fonts when »tnum« on and »lunm« off — and in Infant without any Opentype features.

Capital letters modified by »calt« could not be changed with »smcp«.

Diacritics of the small-caps version of ǜ were too skinny in regular, medium and demi-bold weights, both with and without »ss02«.

»ss03« was not applied to italic ḡ.

Applying »ss02+ss04« to ä, ö and ü yielded inconsist results in Regular and Infant.

Unlike Л and Ф, л and ф were modified by »smcp(bg)«, but not »ss10+smcp«.

In both Regular and Infant, »ss02« failed to affect á already modified by »locl(hu)«

»ss03« failed to affect á already modified by »locl(hu)«

»ss05« failed to affect small-caps á and é already modified by »locl(hu)«

»ss07« failed to affect á already modified by »locl(hu)«

In Upright, »ss07« failed to affect á already modified by »locl(hu)«

Italic double dagger looked strange.

Cormorant was missing several space characters.

The new e.ss02 did not appear in Garamond.

»cv0x« only modifed isolated Q.
The same cv0x table modified different characters in different fonts. E.g., »cv03« modified f in (non-italic) Regular, Infant and Garamond, but Q in italic styles (and Upright.)

»cv01« can now force »short-head« f, e.g., in situations where perhaps fä appears a little too cramped.

For comparison: f forced to f.short via letter-by-letter »aalt«, which can be awkward to implement in some contexts.

There are auto-ligatures for Th and TT, but only without diacritics.

Only some diacritical variants of A are modified by »ss01«.

An individual user requested fu ligatures, but the font author fears readability might not be optimnal. Therefore, those ligatures must be enabled explicitly using »dlig«.

In Unicase and SC with »onum+tnum«, currency signs were too tall and the dotted zero’s dot is off-centered.

Should the the small caps-adjusted numerals that are available in SC with »onum+tnum« also be available in Regular with »onum+tnum+smcp«?
