Implementations

impl TextEncoding

pub fn encode_strict(&self, text: &str) -> Result<Vec<u8>, char>

Strict encoding: returns Err(char) for the first codepoint the encoding cannot represent. Unlike [encode], does NOT silently substitute ? for unmappable characters — callers that must refuse to emit corrupt output (e.g. form-field appearance streams) use this path to produce explicit errors instead of silent garbage.

Contract per encoding:

• WinAnsiEncoding: every Unicode codepoint in the Windows-1252 repertoire is representable; every other codepoint fails.
• MacRomanEncoding: same idea over the Mac Roman repertoire.
• StandardEncoding / PdfDocEncoding: accepts only the ASCII range 0x00..=0x7F (the safe lowest-common-denominator — the lossy UTF-8 passthrough used by encode would silently produce garbage for non-ASCII here).
