pub enum Glyph<'a> {
    Outline(OutlineGlyph),
    Type3(Box<Type3Glyph<'a>>),
}

A glyph defined by an outline.

Type3(Box<Type3Glyph<'a>>)

Implementations

impl Glyph<'_>

pub fn as_unicode(&self) -> Option<BfString>

Returns the Unicode code point for this glyph, if available.

This method attempts to determine the Unicode character that this glyph represents. The exact fallback chain depends on the font type:

For Outline Fonts (Type1, TrueType, CFF):

1. ToUnicode cmap
2. Glyph name → Unicode (via Adobe Glyph List)
3. Unicode naming conventions (e.g., “uni0041”, “u0041”)

For CID Fonts (Type0):

1. ToUnicode cmap

For Type3 Fonts:

1. ToUnicode cmap

Returns None if the Unicode value could not be determined.

Please note that this method is still somewhat experimental and might not work reliably in all cases.
