Mojo module

codepoint

Unicode codepoint handling.

This module provides the Codepoint type for representing single Unicode scalar values. A codepoint represents a single Unicode character, restricted to valid Unicode scalar values in the ranges 0 to 0xD7FF and 0xE000 to 0x10FFFF inclusive.

The Codepoint type provides functionality for:

Converting between codepoints and UTF-8 encoded bytes
Testing character properties like ASCII, digits, whitespace etc.
Converting between codepoints and strings
Safe construction from integers with validation

Example:

    from collections.string import Codepoint
    from testing import assert_true

    # Create a codepoint from a character
    var c = Codepoint.ord('A')

    # Check properties
    assert_true(c.is_ascii())
    assert_true(c.is_ascii_upper())

    # Convert to string
    var s = String(c)  # "A"
    from collections.string import Codepoint
    from testing import assert_true

    # Create a codepoint from a character
    var c = Codepoint.ord('A')

    # Check properties
    assert_true(c.is_ascii())
    assert_true(c.is_ascii_upper())

    # Convert to string
    var s = String(c)  # "A"
