chardet
Universal character encoding detector for Python with built-in language and MIME type detection.
msgpack
A reflect-based MessagePack encoder and decoder for Go with struct tag support, custom extensions, and a sync.Pool-backed API for allocation-light serialization.
bytemuck
A zero-cost, no_std Rust crate for safely casting between plain data types and reinterpreting slices as bytes.
Uppy
Extensible file upload widget with drag-drop, resumable uploads, and remote providers
encoding_rs
Fast, WHATWG-compliant character encoding conversion crate that powers Firefox's Web-facing text decoding.
chardet
Detects the character encoding of a buffer or file using statistical byte-occurrence analysis, with zero dependencies.
base-x
Fast base encoding and decoding for any custom alphabet, using bitcoin-style leading zero compression.
chardetng
A no_std character encoding detector for legacy Web content, built to give Firefox parity with Chrome's ced on undeclared charsets.
webencodings
Python implementation of the WHATWG Encoding standard for resolving legacy web character-encoding labels.
@scure/base
Audited, zero-dependency base16/32/58/64 and bech32/bech32m encoding for TypeScript
isBinaryFile
Detects whether a file or buffer is binary or text in Node.js, similar to Perl's -B switch, with encoding hints for accurate UTF-16, Latin-1, and CJK detection.
encoding
A high-performance, drop-in Go replacement for encoding/json, with fast ASCII, ISO8601, Protobuf, and Thrift codecs.
pylatexenc
A dependency-free Python library that parses LaTeX markup and converts between LaTeX code and Unicode text.
bs58
Base58 encoding and decoding for Bitcoin and other cryptocurrency addresses.
xz2-rs
Rust bindings to liblzma providing streaming and raw in-memory XZ/LZMA compression and decompression.
hashids
Small PHP library to generate short, reversible YouTube-like IDs from numbers.
miniz_oxide
Pure-Rust DEFLATE, zlib, and gzip compression and decompression with no unsafe code and no_std support.
