pub fn utf16_position(text: &str, offset: u32) -> (u32, u32)Expand description
A byte offset as a zero-based line and UTF-16 character offset.
UTF-16 because that is what LSP specifies by default, and getting it wrong is invisible until
somebody writes an emoji in a string literal — which beck-syntax’s own security tests say they
will. SourceMap::line_col counts characters and is one-based, so it is the wrong unit twice
over and is deliberately not used here.
