Enum FaceEncoding 

pub enum FaceEncoding {
    Unicode,
    Latin1,
    AppleRoman,
    AdobeCustom,
    Symbol,
    Other,
}

The fxge-level encodings a font face’s charmap may declare, which are a different set from FontEncoding and are reverse-mapped through the raw tables (CharCodeFromUnicodeForEncoding, the former working note).

Variants

Unicode

The charmap is Unicode: a code is its character.

Latin1

Latin-1, read through the WinAnsi table. The standard-14 encoder in pdfrum-edit (EmbeddedFont::encode) is its production caller.

AppleRoman

Apple Roman, read through the MacRoman table.

AdobeCustom

Adobe custom, read through the PDFDoc table.

Symbol

Microsoft symbol.

Other

Anything else: reverse lookup always yields 0.

Implementations

impl FaceEncoding

pub fn charcode_from_unicode(self, unicode: u16) -> u32

Find the character code this face encoding gives unicode, or 0.

A linear scan returning the first index, and 0 on a miss — which is indistinguishable from a real hit at code 0, exactly as PDF_FindCode leaves it. Callers test != 0, so code 0 is unreachable through this route by construction.
