Apple HFS+ NFD-like Unicode Normalization Library for Rust

HFS+, the file system formerly used in Apple macOS, uses a unique Unicode normalization similar to NFD.

• https://developer.apple.com/library/archive/technotes/tn/tn1150table.html
• https://developer.apple.com/library/archive/technotes/tn/tn1150.html

This library composes or decomposes Unicode code points according to the normalization. e.g.

• Université[U+00E9] de Paris (Common) ⇔ Université[U+0065 U+0301] de Paris (HFS+)
• アップ[U+30D7]ル (Common) ⇔ アップ[U+30D5 U+309A]ル (HFS+)

How to use

Add this library hfs_nfd to your Cargo.toml.

```toml [dependencies] anotherlibrary1 = "" anotherlibrary2 = ""

snip

hfs_nfd = "1.0.0" # <= Here

snip

```

Then, use these functions:

```rust use hfsnfd::{composefromhfsnfd,decomposeintohfs_nfd};

asserteq!(decomposeintohfsnfd("Universit\u{00E9}"), "Universite\u{0301}".tostring()); asserteq!(composefromhfsnfd("アッフ\u{309A}ル"), "アッ{30D7}ル".tostring()); ```
