    #unicode-data

    Unicode Character Database lookup, general categories, East Asian width, binary properties (White_Space, Alphabetic, Lowercase, Uppercase, XID_Start, XID_Continue), and case mapping for MoonBit. This module uses Unicode 18.0.0 data.

    See the repository root README for API documentation and examples.

    #Low-level data packages

    Import the package for the lookup you need. Each package owns its generated tables and exposes lookup functions; the tables themselves remain private.

    moonbit-community/unicode-data/data remains a compatibility package that re-exports the old lookup functions with deprecation notices pointing to these packages. The high-level moonbit-community/unicode-data interface is unchanged: its general_category(c) returns GeneralCategory, with GeneralCategoryGroup available through .group(). These enums remain defined in the root package. The low-level general_category package retains lookup_general_category(c) -> Int, returning the existing 0–29 category ordinals.

    east_asian_width

    source
    fn east_asian_width(c : Char) -> EastAsianWidth

    Get the East_Asian_Width for a character.

    East_Asian_Width classifies characters by the width they have in East Asian typography. It is a property of a single character, not a column count: nonspacing marks and control characters have a value too. Code points the Unicode Character Database does not list are Neutral, except that unassigned code points in the CJK ideograph blocks and in planes 2 and 3 are Wide.

    general_category

    source
    fn general_category(c : Char) -> GeneralCategory

    Get the General_Category for a character

    is_alphabetic

    source
    fn is_alphabetic(c : Char) -> Bool

    Check whether a character has the Unicode Alphabetic property.

    Alphabetic covers the letters (General_Category L), letter numbers (Nl), and Other_Alphabetic characters such as the vowel signs of Indic scripts. Decimal digits are not Alphabetic.

    is_lowercase

    source
    fn is_lowercase(c : Char) -> Bool

    Check whether a character has the Unicode Lowercase property.

    Lowercase is broader than General_Category Ll: it also covers Other_Lowercase characters such as U+00AA FEMININE ORDINAL INDICATOR, modifier letters like U+02B0, and the small Roman numerals. Titlecase letters (Lt) are neither Lowercase nor Uppercase.

    is_uppercase

    source
    fn is_uppercase(c : Char) -> Bool

    Check whether a character has the Unicode Uppercase property.

    Uppercase is broader than General_Category Lu: it also covers Other_Uppercase characters such as the capital Roman numerals and the circled capital Latin letters. Titlecase letters (Lt) are neither Lowercase nor Uppercase.

    is_white_space

    source
    fn is_white_space(c : Char) -> Bool

    Check whether a character has the Unicode White_Space property.

    White_Space covers the ASCII controls TAB, LF, VT, FF, and CR, the space separators (General_Category Zs), U+0085 NEXT LINE, and the line and paragraph separators U+2028 and U+2029. It does not include U+200B ZERO WIDTH SPACE or U+FEFF ZERO WIDTH NO-BREAK SPACE.

    is_xid_continue

    source
    fn is_xid_continue(c : Char) -> Bool

    Check whether a character has the Unicode XID_Continue property.

    XID_Continue is the recommended continuation class for Unicode default identifiers and includes every XID_Start character.

    is_xid_start

    source
    fn is_xid_start(c : Char) -> Bool

    Check whether a character has the Unicode XID_Start property.

    XID_Start is the recommended start class for Unicode default identifiers.

    to_lowercase

    source
    fn to_lowercase(c : Char) -> String

    Get the full lowercase mapping for a character Returns a String containing one or more lowercase characters For example, 'İ' (U+0130) maps to "i\u{0307}" (i with combining dot above)

    to_simple_lowercase

    source
    fn to_simple_lowercase(c : Char) -> Char

    Get the simple lowercase mapping for a character Returns the character itself if no mapping exists

    to_simple_titlecase

    source
    fn to_simple_titlecase(c : Char) -> Char

    Get the simple titlecase mapping for a character Returns the character itself if no mapping exists

    to_simple_uppercase

    source
    fn to_simple_uppercase(c : Char) -> Char

    Get the simple uppercase mapping for a character Returns the character itself if no mapping exists

    to_titlecase

    source
    fn to_titlecase(c : Char) -> String

    Get the full titlecase mapping for a character Returns a String containing one or more titlecase characters For example, 'ß' (U+00DF) maps to "Ss", and 'ffi' (U+FB03) maps to "Ffi"

    to_uppercase

    source
    fn to_uppercase(c : Char) -> String

    Get the full uppercase mapping for a character Returns a String containing one or more uppercase characters For example, 'ß' (U+00DF) maps to "SS", and 'ffi' (U+FB03) maps to "FFI"
