Previous questions and outline of needs
Several questions have been asked, especially for polytonic Greeek – especially ‘What are popular fonts for polytonic Greek?’ and ‘Greek font with legible diacritics’ – but neither of them cover my needs. I am quite a big fan of EB Garamond, which is my go-to font for any kind of academic writing, but in my online writing, I very often need numerous diacritics, such as combining dot below. Further a font-family with both a sans-serif and a regular type is desirable for this kind of writing (ɔ: online).
My main needs are:
- Full Latin extended support, upper and lower case, including æ, ø, å; ä, ö; þ, ð; double accent (ő); &c.
- Full polytonic Greek support, including macrons, breve symbols, iota subscript, both breath marks and all tone marks.
- Special characters, such as explanation symbol (‘that is’ symbol: ‘ɔ:’ (open o: U+254)); regular symbols like degrees, proper primes; and preferably also weight symbols for pound and ounce (℔ and ℥), but that would be a bonus.
Specimens and issues with these
EB Garamond is not a big fan of combining dot below, which I use for poetry (ictus). Another font which I find very pleasing, is the Alegreya family, especially since it has both regular and sans-serif types.
Here are some samples (the sample text below is ‘Æýūøĭọ ἄνυροπος’ [Sorry about that, folks; it is two in the morning, and it was supposed to say ἄνθρωπος – well, it still gets the job done, even though it’s gibberish.]):
Baskerville stands out as a no-go: Though it looks excellent on-screen, it has no support for Greek. The other ones all look fine. EB Garamond generally isn’t that great on-screen (it never was designed for it), though it does work if set larger; Liberata is quite fat, but does work on-screen; but both of these only come as seriffed, which make them rather undesirable for my needs. Alegreya and Source Pro are both good candidates, as they come in both seriffed and sans-serif styles; they both support Greek polytonic, though Source Sans Pro does not. However, these too both have lacking support diacritics. The option I have used thus far, is OpenSans, which is yielding this mess:
Notice the i with a macron floating on top of it; the u with a macron which is in a different font – the fallback font; and, in fact, this is true for every single example of a vowel (and I am assuming consonants as well) with an extra diacritic underneath: The vowel is changed to the fallback font, which can be seen when compared to vowels with no diacritic or only a macron.
Even in LibreOffice, with all the necessary OpenType features switched on, it doesn’t look desirable:
Notice how ī with combining dot below constantly gets messed up. With the serif specimen, it is at least somewhat acceptable, but with the sans-serif, it is simply not.
Which fonts are good options for full support of Latin extended with diacritics, as well as polytonic Greek? Open source fonts (free of charge, fully featured) are preferable. Optionally, if no such fonts exist, what are good fonts to pair, that is: a good font for the Latin plus diacritics and a good font for Greek to go with it?
