I’ll be especially interested in seeing how Font Book behaves in Ventura on an Apple Silicon Mac, and if it’s anything like what I’ve written about it on an Intel Mac. New M2 mini is on order and I’ll be able to catch up on testing I couldn’t do before.

It should be noted that this article is written around the assumption that you are using English as your primary language. This article will benefit prepress operators and graphic designers the most, but can clear up font issues for most general users as well. The idea is to keep your font list as small as possible to avoid font conflicts (font conflicts are explained in Section 9). Its main purpose is to show you where fonts are located on your system and which can be safely deactivated (where applicable). Inside FontLab, each glyph includes some metadata such as a name or a Unicode, and consists of one or more layers.This article deals with font usage in Big Sur 11.x through Ventura 13.x. For example, “twocents”, “a1”, and “ _” are valid glyph names, while “2cents” and “.twocents” are not. Other characters such as spaces are not permitted! A glyph name must start with a letter or the underscore character – with the exception of the special glyph name “.notdef” that starts with the period. Both the base name and the suffix may only include: uppercase English letters (A-Z), lowercase English letters (a-z), European digits (0–9), and underscore ( _). The glyph name consists of a base name, optionally followed by a period (.), which is then followed by a suffix. Glyph name limitations »Ī glyph name must not be longer than 31 characters. Some glyphs in a font may have no Unicode codepoint but every glyph must have a unique name. For example, the default ampersand should have the Unicode codepoint U+0026. Additionally, many or all glyphs in a font are encoded, which means that the glyph is the default for a given Unicode character or codepoint. Glyphs in most fonts also have glyph names, which are brief ASCII text labels without spaces (for example, the glyph name for “&” is “ampersand”). Every glyph in a font has a Glyph ID or index, which is the physical numbering of the glyphs in the font (starting at zero, so if there are 27 glyphs in a font, they have Glyph IDs 0–26). Glyphs are identified in several different ways. For instance in a handwriting font, each variant of the character A would be a distinct glyph. Note that all glyphs are unique, even if they represent different forms of the same character. A glyph can be a default typographic representation of a character (if it has a Unicode codepoint assigned), or a variant typographic representation of one or more characters, or a constituent of another glyph, or a combined form of two or more glyphs (then they’re accessed via typographic features or composites). Glyph »Ī glyph is the basic element of the font, occupying a “slot” in the font. In simple cases, there is one glyph for each supported character. For example, the Latin A, the Cyrillic А and Greek capital Alpha Α, all look the same but represent different characters from different scripts.Ī character that is supported in a font must have some way of being represented by the glyphs in the font. The same character can be written or drawn differently based on styles:Īt the same time, sometimes characters may look the same, yet represent different characters. These codes are used to store text data on a computer, and also used to reference the glyphs in a font. The primary standard for such codes is Unicode, a universal character encoding standard with over 100,000 defined characters so far. it has a number or code assigned to it in some standard, so that it can be referenced in the same way across fonts. In font terminology, something is a character if it is encoded, i.e. Both concepts are explained below: Character »Ī character is the minimal unit of the written language – a part of the alphabet, a symbol, a digit. The distinction between character and glyph is critical to understanding FontLab, and fonts in general.
