Prior to version 0.1.11, the public parser entrypoint `ratex_parser::parse(\u0026str)` panics on the 9-byte input `\\verbéxé` (i.e. `\\verb` followed by the non-ASCII delimiter `é`). When handling a `\\verb` command, the parser slices the verbatim argument with byte indices (`arg[1..arg.len() - 1]`); if the delimiter character is multibyte UTF-8, index `1` lands inside that character and Rust panics with *“byte index 1 is not a char boundary”*. Because RaTeX’s release profile sets `panic \u003d \"abort\"` (`Cargo.toml:48`), the panic aborts the entire process — not just the current request/thread — making this a hard denial of service for any service that renders untrusted LaTeX.
