Here’s an interface that @Eric tells me has been useful for him, a transliteration interface for converting between many orthographies used for various reasons for Zenzontepec Chatino.
Any thoughts? Suggestions? I’m planning to create a more generic version of this where the transliteration table is editable. There are of course also some kinds of transliteration relationships that are tricky to represent with a simple table data mode like this, but by the same token there are many situations where the relationships are pretty straightforward, and a tool like this can alleviate some pain.
