Technical. JLTF fonts are carefully prepared to meet today’s advanced typographical needs in terms of both design and technology. We offer a variety of different font formats to ensure the use of fonts in different environments.

Glyph
Is a character with a specified form. The “A” character, for example, is not a glyph itself if you don’t count its detailed outlook. The “A” character has many different forms such as Roman, Italic or Swash. All these variations of the character “A” are called glyphs.

Font
Is set of glyphs in certain style such as Xtra Sans Bold Italic. However, whole typefaces are nowadays often called fonts as well.

LF & SC fonts
LF abbreviation in font’s name means that one has lining figures. Lining figures and upper case letters have same optical height. Fonts which contain small caps letters are marked with SC abbreviation.

Typeface
Traditionally this means just the “face” of a printing block. Nowadays, it tends to describe a set of fonts sharing the same general characteristics such as all fonts of Xtra Sans.

Type family
An even larger set of fonts than typeface. A group of typefaces with unifying style. Xtra Sans, Xtra Sans Condensed and Xtra Sans Narrow would be called a type family.

Kerning
Kerning means a special spacing between two glyphs. Even if general character spacing is done with great care, additional kerning is needed to keep text smooth. Because of the many kerning pairs in JLTF fonts you may freely set text in all cases. Upper case, lower case, small caps or accented characters all go smoothly together.

Character Set
The character set is the selection of different glyphs in one font file. Fonts may contain different amounts of glyphs according to their format. PostScript and TrueType fonts include up to 256 glyphs, which covers all necessary characters for a limited language group. OpenType file may contain up to 65 535 glyphs, and they may thus provide characters for much larger language group than PostScript or TrueType.

Xtra Sans OpenType and PostScript fonts include similar character set. This basic set covers all characters in Western and Northern European languages.
 
Tanger Serif OpenType fonts includes expanded character set (supports all European languages using Latin characters), small caps, old style figures, ligatures, fractions etc. All these are easily accessed through OpenType features. Each of these fonts contain close to 600 glyphs.
 
If you have any questions concernign our fonts character sets or language support, please don't hesitate to ask.

Character Encoding
Character encodings (algorithms) are methods to build and manage character sets in computer systems.
