osobhandClaude Opus 5.5 bd36fe883b fix(format): flag non-ASCII link names as UTF-8

The writer marked every link name ASCII, so a name such as "größe" was
stored as UTF-8 bytes under the ASCII character set (h5py reports cset 0
for it). Names that are not plain ASCII now carry the UTF-8 flag, as h5py
writes them; ASCII names are unchanged.

clawhdf5-format

Pure-Rust HDF5 binary format parsing and writing — no C dependencies.

Features

Zero-copy superblock, object header, and B-tree parsing
Chunked dataset read/write with filter pipelines
no_std support (disable std feature)
Optional parallel reads via Rayon
SHA-256 provenance tracking

Usage

use clawhdf5_format::Superblock;

let data = std::fs::read("data.h5").unwrap();
let sb = Superblock::from_bytes(&data).unwrap();
println!("HDF5 version {}.{}", sb.version_major(), sb.version_minor());
