Sigma
Sigma ('sɪgmə; uppercase Σ, lowercase σ, lowercase in word-final position ς; σίγμα) is the eighteenth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 200. In general mathematics, uppercase Σ is used as an operator for summation. When used at the end of a letter-case word (one that does not use all caps), the final form (ς) is used. In Ὀδυσσεύς (Odysseus), for example, the two lowercase sigmas (σ) in the center of the name are distinct from the word-final sigma (ς) at the end.
Œ
Œ (minuscule: œ) is a Latin alphabet grapheme, a ligature of o and e. In medieval and early modern Latin, it was used to represent the Greek diphthong οι and in a few non-Greek words, usages that continue in English and French. In French, it is also used in some non-learned words, representing then mid-front rounded vowel-sounds, rather than sounding the same as é or è, those being its traditional French values in the words borrowed from or via Latin.
Epsilon
Epsilon (ˈɛpsᵻlɒn, UKalsoɛpˈsaɪlən; uppercase Ε, lowercase ε or lunate ε; έψιλον) is the fifth letter of the Greek alphabet, corresponding phonetically to a mid front unrounded vowel e̞ or ɛ̝. In the system of Greek numerals it also has the value five. It was derived from the Phoenician letter He . Letters that arose from epsilon include the Roman E, Ë and Ɛ, and Cyrillic Е, È, Ё, Є and Э.
Braille
Braille (breɪl , bʁɑj) is a tactile writing system used by people who are visually impaired, including people who are blind, deafblind or who have low vision. It can be read either on embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser. Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident.

Cherokee syllabary
The Cherokee syllabary is a syllabary invented by Sequoyah in the late 1810s and early 1820s to write the Cherokee language. His creation of the syllabary is particularly noteworthy as he was illiterate until the creation of his syllabary. He first experimented with logograms, but his system later developed into a syllabary. In his system, each symbol represents a syllable rather than a single phoneme; the 85 (originally 86) characters provide a suitable method for writing Cherokee.
Chi (letter)
Chi 'kaɪ,_"xi: (uppercase Χ, lowercase χ; χῖ) is the twenty-second letter of the Greek alphabet. Its value in Ancient Greek was an aspirated velar stop /kh/ (in the Western Greek alphabet: /ks/). In Koine Greek and later dialects it became a fricative ([x]/[ç]) along with Θ and Φ. In Modern Greek, it has two distinct pronunciations: In front of high or front vowels (/e/ or /i/) it is pronounced as a voiceless palatal fricative [ç], as in German ich or like the h in some pronunciations of the English words hew and human.
Dollar sign
The dollar sign, also known as peso sign, is a currency symbol consisting of a capital "S" crossed with one or two vertical strokes () and the United States dollar (US$): in local use, the nationality prefix is usually omitted.
Legibility
Legibility is the ease with which a reader can decode symbols. In addition to written language, it can also refer to behaviour or architecture, for example. From the perspective of communication research, it can be described as a measure of the permeability of a communication channel. A large number of known factors can affect legibility. In everyday language, legibility is commonly used as a synonym for readability. In graphic design, however, legibility is often distinguished from readability.
Block letters
Block letters (known as printscript, manuscript, print writing or ball and stick in academics) are a sans-serif (or "gothic") style of writing Latin script in which the letters are individual glyphs, with no joining. Elementary education in English-speaking countries typically introduces children to the literacy of handwriting using a method of block letters (commonly referred to as manuscript by educators), which may later advance to cursive (joined) penmanship.
