From the book Historia de Gentibus Septentrionalibus (A Description of the Northern Peoples), available on Google Books:
What are the two highlighted letters in Unicode?
What typeface is this? Maybe Antiqua?
The first one is a common abbreviation:
q; stands for que in this case. A screenshot from Cappelli:
The other one is a ligature: what you see is simply
ct with a little arc connecting the letters.
I don't know whether these exist in Unicode, nor do I know about type faces.
While the two previous answer gave an identification of the character, none seems to give the unicode codepoint of the first (the second is a ligature and not encoded, just an ordinary c and t together. The que abreviations is q, followed by ꝫ U+A76B LATIN SMALL LETTER ET. It was proposed in L2/06101 with its capital counterpart Ꝫ U+A76A LATIN CAPITAL LETTER ET and many other medieval abbreviation characters. Many of these cribal abbreviations are encoded in the Latin Extended-D block.
Your examples would be
and the ones of @shoover whould be, in pure unicode text,
The typeface appears similar to those by Nicolas Jenson, a 15th-century typographer.
The original typeface may not have a name (or the name may be lost to time), but there is a 21st-century typographer named Gilles Le Corre (GLC) who creates fonts that replicate 15th- and 16th-century typefaces.
None of GLC's typefaces matches this one exactly, but several of them are quite close.
1470 Jenson Latin Bold has a Q with the same long tail, lowercase e with slanted crossbar, and ct ligature, but its -que ligature is different. Also, you can't get the -que ligature without the in- and -us ligatures, as seen in this sample.
1529 Champ Fleury Pro has a Q with a shorter tail and is a little more angular than Jenson Latin. The lowercase e has a slanted crossbar, and the ct ligatures is used by default, but the ae and interior s ligatures require typing a special character. It doesn't appear to have a -que ligature.
1543 Humane Jenson Bold has a slightly shorter Q-tail than Jenson Latin. It also has the slanted-crossbar e, but doesn't use the ligatures by default. The ct and que ligatures are actually occupying the slots of dagger and double-dagger, and the que ligature has a diacritical.
1543 Humane Petreius has a short Q-tail, but a slanted e-crossbar, a ct ligature, and a lovely que ligature (in the double-dagger slot).
Yes, this question is off-topic and will probably get closed. I have no vested interest in the MyFonts website.
