About Czech letters
Czech uses the acute for long vowels, the caron (háček) on consonants and ě, and the ring on ů.
The Czech QWERTZ layout puts ě, š, č, ř, ž, ý, á, í, é on the number row, with the number typed using Shift.
On a Mac, the ABC Extended layout types a caron with Option+V then the letter.
