A cross is a geometrical figure consisting of two intersecting lines or bars, usually perpendicular to each other. The lines usually run vertically and horizontally. A cross of oblique lines, in the shape of the Latin letter X, is termed a saltire in heraldic terminology.
Phi is the twenty-first letter of the Greek alphabet.
Pi is the sixteenth letter of the Greek alphabet, meaning units united, and representing the voiceless bilabial plosive IPA:[p]. In the system of Greek numerals it has a value of 80. It was derived from the Phoenician letter Pe. Letters that arose from pi include Latin P, Cyrillic Pe, Coptic pi, and Gothic pairthra (𐍀).
The tilde˜ or ~, is a grapheme with a number of uses. The name of the character came into English from Spanish, which in turn came from the Latin titulus, meaning 'title' or 'superscription'. Its primary use is as a diacritic (accent) in combination with a base letter; but, for historical reasons, it is also used in standalone form within a variety of contexts.
The multiplication sign, also known as the times sign or the dimension sign, is a mathematical symbol used to denote the operation of multiplication, which results in a product. While similar to a lowercase X, the form is properly a four-fold rotationally symmetric saltire.
Sigma 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, 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. The Latin letter S derives from sigma while the Cyrillic letter Es derives from a lunate form of this letter.
The Tamil script is an abugida script that is used by Tamils and Tamil speakers in India, Sri Lanka, Malaysia, Singapore, Indonesia and elsewhere to write the Tamil language. It is one of the official scripts of the Indian Republic. Certain minority languages such as Saurashtra, Badaga, Irula and Paniya are also written in the Tamil script.
The bilabial clicks are a family of click consonants that sound like a smack of the lips. They are found as phonemes only in the small Tuu language family, in the ǂ’Amkoe language of Botswana, and in the extinct Damin ritual jargon of Australia. However, bilabial clicks are found paralinguistically for a kiss in various languages, including integrated into a greeting in the Hadza language of Tanzania, and as allophones of labial–velar stops in some West African languages, as of /mw/ in some of the languages neighboring Shona, such as Ndau and Tonga.
A sun cross, solar cross, or wheel cross is a solar symbol consisting of an equilateral cross inside a circle.
Unicode has a certain amount of duplication of characters. These are pairs of single Unicode code points that are canonically equivalent. The reason for this are compatibility issues with legacy systems.
Ø is a Scandinavian vowel letter.
Circled plus (⊕) or n-ary circled plus (⨁) may refer to:
The Unicode Consortium and the ISO/IEC JTC 1/SC 2/WG 2 jointly collaborate on the list of the characters in the Universal Coded Character Set. The Universal Coded Character Set, most commonly called the Universal Character Set, is an international standard to map characters, discrete symbols used in natural language, mathematics, music, and other domains, to unique machine-readable data values. By creating this mapping, the UCS enables computer software vendors to interoperate, and transmit—interchange—UCS-encoded text strings from one to another. Because it is a universal map, it can be used to represent multiple languages at the same time. This avoids the confusion of using multiple legacy character encodings, which can result in the same sequence of codes having multiple interpretations depending on the character encoding in use, resulting in mojibake if the wrong one is chosen.
In Unicode and the UCS, a compatibility character is a character that is encoded solely to maintain round-trip convertibility with other, often older, standards. As the Unicode Glossary says:
A character that would not have been encoded except for compatibility and round-trip convertibility with other standards
The Cyrillic O variants, consisting of Monocular O, Binocular O, Double monocular O, and Multiocular O are rare glyph variants of Cyrillic letter O. In 2007, they were proposed for inclusion into Unicode.
The null sign (∅) is often used in mathematics for denoting the empty set. The same letter in linguistics represents zero, the lack of an element. It is commonly used in phonology, morphology, and syntax.
I, or i, is the ninth letter and the third vowel letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is i, plural ies.
B, or b, is the second letter of the Latin-script alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is bee, plural bees. It represents the voiced bilabial stop in many languages, including English. In some other languages, it is used to represent other bilabial consonants.
