About my favourite Czech typographer:

Náchodský (plhovský) rodák Oldřich Hlavsa se v letech 1924–1928 vyučil typografem v Náchodě u Václava Rydla, tehdy samozřejmě v klasické ruční tiskárně, v době, kdy typografové velmi dbali na úroveň a čest svého řemesla. Pracoval pak v několika dalších náchodských tiskárnách. V roce 1934 na sebe upozornil v soutěži na plakát. Koncem třicátých let odešel do Prahy jako faktor do tiskárny Solidarita. Od čtyřicátých let graficky upravoval prestižní časopis Typografia, který ovlivňoval lepší část českého tisku. Od r. 1950 byl členem Svazu čs. výtvarných umělců, v polovině padesátých let se stal samostatným výtvarníkem a věnoval se převážně knižní typografii.

My version of Georgia doesn't support a lot of those Czech characters, so they're defaulting to Arial in my browser.

Anybody else have that problem?

Yer, same here. It’s not Arial tho.

Arial? My browser decided to default to something that looks like Zapfino.  :-|

no one for Icelandic and Greenlandic please?

Try this from wikipedia about typography (icleandic):

Leturfræði er myndlist sem samanstendur af letursetningu, leturhönnun, og breytingu tákna. Leturtákn eru sköpuð og breytt með ýmsum aðferðum. Letursetning varðar um val stafagerða, leturstærð, línulengd, línuþéttleiki, leturþjöppun og stafþjöppun.

Leturfræði og prentlist eru yfirleitt framkvæmd af letursetjarum, grafískum hönnuðum, listrænu stjornandum. Þangað til í dag var prentlist sérhæfð atvinnugrein en í dag tölvur geta yfirtekið margar aðferðir prentlistar.

What an interesting challenge to find typographic text in Greenlandic!

Short of finding a Greenlandic speaker here on Typophile (which may not be unlikely) your best bet might be one of the following:

A site that has English-Greenlandic-French text about a downloadable Greenlandic font

This languages website has a 'contact me' button where you could e-mail and ask them to write a short paragraph in Greenlandic perhaps?

Hope that's helpful ;)

I'm afraid this isn't Greenlandic (Kalaallisut). There is much in common with Inuktitut (and dialects thereof) and Kalaallisut, but the relevant issue here is of orthography. Kalaallisut uses only the letters: [a e f g i j k l m n o p q r s t u v] in upper- or lowercase, plus standard numerals and punctuation (inc. guillemot). In terms of supporting any ‘extra’ diacritics, language support for Danish would be more relevant.

Older (pre-early 1970's) did use some diacritics and the ‘kra’ (voiceless uvular plosive) [ĸ], so the only environment in which it would be used would be to reproduce older texts, unless there's another spelling reform. Nowadays, as in Latin-based Inuktitut orthographies, the ‘q’ is used.

I think you may have a difficult time finding texts in Kalaallisut that talk about typography, but you never know.
