# CTFontGetGlyphsForCharacters(_:_:_:_:) Performs basic character-to-glyph mapping. ``` func CTFontGetGlyphsForCharacters(_ font: CTFont, _ characters: UnsafePointer, _ glyphs: UnsafeMutablePointer, _ count: CFIndex) -> Bool ``` ## Parameters `font` The font reference. `characters` An array of Unicode characters. `glyphs` On output, points to an array of glyph values. `count` The capacity of the character and glyph arrays. ## Return Value `True` if the font could encode all Unicode characters; otherwise `False`. ## Discussion Provides basic Unicode encoding for the given font, returning by reference an array of values corresponding to a given array of Unicode characters for the given font. If a glyph could not be encoded, a value of `0` is passed back at the corresponding index in the `glyphs` array and the function returns `False`. It is the responsibility of the caller to handle the Unicode properties of the input characters. --- Copyright © 2026 Apple Inc.
