Info

Multiple, discontinuous ranges can be specified, separated by a comma. As with other comma-separated lists in CSS, any whitespace [p. 37] before or after the comma is ignored. [p. 42] For example: unicode-range: U+370-3FF, U+1F?? This covers the range 0370 to 03FF (Modern Greek) plus 1F00 to 1FFF (Ancient polytonic Greek). unicode-range: U+3000-303F, U+3100-312F, U+32??, U+33??, U+4E00-9FFF, U+F9000-FAFF, U+FE30-FE4F Something of a worst case in terms of verbosity, this very precisely indicates that this (extremely large) font contains only Chinese characters from ISO 10646, without including any characters that are uniquely Japanese or Korean. The range is 3000 to 303F (CJK symbols and punctuation) plus 3100 to 312F (Bopomofo) plus 3200 to 32FF (enclosed CJK letters and months) plus 3300 to 33FF (CJK compatibility zone) plus 4E00 to 9FFF (CJK unified Ideographs) plus F900 to FAFF (CJK compatibility ideographs) plus FE30 to FE4F (CJK compatibility forms). A more likely representation for a typical Chinese font would be: unicode-range: U+3000-33FF, U+4E00-9FFF unicode-range: U+11E00-121FF This font covers a proposed registration for Aztec pictograms, covering the range 1E00 to 21FF in plane 1. unicode-range: U+1A00-1A1F This font covers a proposed registration for Irish Ogham covering the range 1A00 to 1A1F 15.3.4 Descriptor for Numeric Values: ’units-per-em’ The following descriptor specifies the number of "units" per em; these units may be used by several other descriptors to express various lengths, so ’units-per-em’ is required if other descriptors depend on it. ’units-per-em’ (Descriptor) Value: Initial: undefined Media: visual This is the descriptor for the number of the coordinate units on the em square [p. 227] , the size of the design grid on which glyphs are laid out. 15.3.5 Descriptor for Referencing: ’src’ This descriptor is required for referencing actual font data, whether downloadable or locally installed. ’src’ (Descriptor) 218
Value: [ [format( [, ]*)] | ] [, [format( [, ]*)] | ]* Initial: undefined Media: visual This is a prioritized, comma-separated list of external references and/or locally installed font face names. The external reference points to the font data on the Web. This is required if the WebFont is to be downloaded. The font resource may be a subset of the source font, for example it may contain only the glyphs needed for the current page or for a set of pages. The external reference consists of a URI, followed by an optional hint regarding the format of font resource to be found at that URI, and this information should be used by clients to avoid following links to fonts in formats they are unable to use. As with any hypertext reference, there may be other formats available, but the client has a better idea of what is likely to be there, in a more robust way than trying to parse filename extensions in URIs. The format hint contains a comma-separated list of format strings that denote well-known font formats. The user agent will recognize the name of font formats that it supports, and will avoid downloading fonts in formats that it does not recognize. An initial list of format strings defined by this specification and representing formats likely to be used by implementations on various platforms is: String "truedoc-pfr" Font Format TrueDoc Portable Font Resource Examples of common extensions .pfr "embedded-opentype" Embedded OpenType .eot "type-1" PostScript Type 1 .pfb, .pfa "truetype" TrueType .ttf "opentype" "truetype-gx" "speedo" "intellifont" OpenType, including TrueType Open TrueType with GX extensions Speedo Intellifont .ttf As with other URIs in CSS [p. 46] , the URI may be partial, in which case it is resolved relative to the location of the style sheet containing the @font-face. The locally-installed is the full font name of a locally installed font. The full font name is the name of the font as reported by the operating system and is the name most likely to be used in reader style sheets, browser default style sheets or possibly author style sheets on an intranet. Adornments such as bold, italic, and underline are often used to differentiate faces within a font family. For more information about full font names [p. 226] please consult the 219
