Rust bindings to the utf8proc library supporting normalization, case-folding, and character class testing.
A statically linked binary is under 350K, yet can replace the functionality of the unicode-width and unicode-normalization crates, among others.
It is used for Unicode implementation in the Julia programming language.
The underlying utf8proc library does not support any "derived properties", including the XID_Start/XID_Continue properties.
For this purpose, the unicode-ident crate is recommended.
It is very fast and needs only ~10KiB of static storage.
Emulating this functionality would be slow and/or require additional static storage.
It also does not support lookup or resolution of character names.
For that, consider the unicode_names2 crate.
The safe bindings does not (yet) wrap all the functionality that the C library does. PRs are welcome.
