- support for Modified Hepburn, Kunreisiki, Nihonsiki systems
- custom overrides for individual mappings
- custom overrides for specific words
- built in exceptions list (Tokyo, Osaka, etc.)
- uses foreign spelling when available in UniDic
- proper nouns are capitalized

Things not supported:
- traditional Hepburn n-to-m: Shimbashi
- macrons or circumflexes: Tōkyō, Tôkyô
- passport Hepburn: Satoh (but you can use an exception)

Internally, cutlet uses fugashi, so you can use the same dictionary you use for normal tokenization.
Cutlet can be installed through pip as usual.
pip install cutlet
Note that if you don't have a MeCab dictionary installed you'll also have to install one. If you're just getting started unidic-lite is probably fine.
pip install unidic-lite
A command-line script is included for quick testing. Just use
cutlet and each
line of stdin will be treated as a sentence. You can specify the system to use
nihon) as the first argument.
