Hi David,

Thanks for your analysis!

This is more than I can do right now, and besides, I'm thinking a different implementation is in order, so that a single anchor isn't used across so many ranges. (It seemed like a good idea at the time, but now I'm regretting it.)

Another thought: since especially the phonetic letters are so scattered, it might be a good idea for me to write a script to investigate which are acutally decorated with anchors...

In any case, it has to be another day.

Teuthonista letters:

  • U+00DF LATIN SMALL LETTER SHARP S
  • U+0111 LATIN SMALL LETTER D WITH STROKE
  • U+0119 LATIN SMALL LETTER E WITH OGONEK
  • U+012F LATIN SMALL LETTER I WITH OGONEK
  • U+0173 LATIN SMALL LETTER U WITH OGONEK
  • U+0180 LATIN SMALL LETTER B WITH STROKE
  • U+01EB LATIN SMALL LETTER O WITH OGONEK

plus everything in the range U+AB30 to U+AB5F

Teuthonista letters above:

  • U+0364 COMBINING LATIN SMALL LETTER E
  • U+0365 COMBINING LATIN SMALL LETTER I
  • U+0366 COMBINING LATIN SMALL LETTER O
  • U+0367 COMBINING LATIN SMALL LETTER U
  • U+0369 COMBINING LATIN SMALL LETTER D
  • U+036A COMBINING LATIN SMALL LETTER H
  • U+036C COMBINING LATIN SMALL LETTER R
  • U+1DDC COMBINING LATIN SMALL LETTER K

plus everything in the range U+1DE7 to U+1DF4

Teuthonista diacritics above:

  • U+0303 COMBINING TILDE
  • U+0304 COMBINING MACRON
  • U+0308 COMBINING DIAERESIS

plus everything in the range U+1AB0 to U+1AB4

Teuthonista diacritics below:

  • U+0323 COMBINING DOT BELOW
  • U+0324 COMBINING DIAERESIS BELOW
  • U+0325 COMBINING RING BELOW
  • U+0329 COMBINING VERTICAL LINE BELOW
  • U+032F COMBINING INVERTED BREVE BELOW
  • U+0330 COMBINING TILDE BELOW

plus everything in the range U+1AB5 to U+1ABA

Teuthonista also uses parentheses overlays. U+1ABB applies to the diacritics above. U+1ABC applies to U+0303. U+1ABD applies to the diacritics below. U+1ABE applies to some letters; its exact position depends on the letter: on U+014B LATIN SMALL LETTER ENG and U+027D LATIN SMALL LETTER R WITH TAIL, the tail is parenthesized; on U+0180 LATIN SMALL LETTER B WITH STROKE, U+0111 LATIN SMALL LETTER D WITH STROKE, and U+01E5 LATIN SMALL LETTER G WITH STROKE, the stroke is parenthesized; and on U+026B LATIN SMALL LETTER L WITH MIDDLE TILDE, the tilde is parenthesized.

Hi David,

I played with of your lists. To put in some anchors is not a problem. The problem is to know what the scope of the application is. I need to know what base characters are used in this applications.

It would be nice to have authoritative lists.

Another technical issue is that many combinations are automatically converted to combined glyphs, so the combined glyphs also have to get anchors. That will be messy.

As to your remarks about two glyphs for one letter: you are looking at this a very different way than I am. To me, there is one glyph, and one or more reference to it. This was of course deliberate. There is a huge advantage in having all the glyphs for an alphabet in one place--this isn't going to change, although I appreciate your point. It's a trade-off.

Thu 13 Apr 2017 06:57:27 PM UTC, original submission:

I searched Wikipedia for diacritics in various phonetic alphabets that didn’t look right in FreeSerif. My findings are listed below. However, phonetic diacritics are productive, and I have certainly missed some combinations. I suggest that you give every phonetic diacritic two anchor points (mark and basemark) and every phonetic letter two anchor points (above and below). I can provide a list of these if that would be helpful.

I also suggest not having two glyphs for a single small capital letter (e.g. sc.u/Usmallcap or sc.y/Ysmallcap): having only one would mean you’d only need to maintain anchor points once per letter instead of twice. The current situation is just asking for bugs.

The following base characters are missing anchor points for diacritics above. For some the diacritics overlap the base, and for others the diacritics are not centered. The uncenterednesses are more obvious in the italic fonts.
