Overview: Text and localization
Text and localization rules connect character representation, language context and display or sorting choices.
A translated title and a sort title can legitimately differ from the original display name. Language tags identify context, while Unicode describes the stored characters. These pages distinguish those roles so a library can preserve the intended text and still organize it appropriately for the viewer.
Unicode metadata
Unicode metadata represents text through defined characters and encodings, while normalization, search keys and locale ordering are separate transformations.Language tags
A language tag identifies a linguistic presentation with applicable language, script, region and extension information, while selection and fallback remain separate policies.Localized titles
Localized titles provide language- or region-associated labels for one work, independently of its original title and scoped catalogue identity.Sort titles
A sort title is a presentation-order key that can differ from the displayed title, with locale, numeric and tie-breaking policies determining the resulting sequence.
