So, to set the scene here, I have a proptest between two libraries set up. One of the libraries usesunicode-normalization under the hood, the othericu_normalizer.

I expected that both output the same values, but my CI exploded at some point on the weird string"\u{11366}\u{113ce}".
When put through the NFC normalizer, you get two different outputs:

1. unicode-normalization:"\u{113ce}\u{11366}"
2. icu_normalizer:"\u{11366}\u{113ce}"

Just a fun little thing I thought I'd report since it's technically a correctness issue (I'm just not good enough with Unicode to determine whether it's an issue with ICU4X or this crate).
