// Conversions should be:
|
|
// 1. complete
|
|
// * convert every sequence of Latin letters (a to z plus apostrophe)
|
|
// to a sequence of Native letters
|
|
// * convert every sequence of Native letters to Latin letters
|
|
// 2. reversable
|
|
// * any string of Native converted to Latin and back should be the same
|
|
// * this is not true for English converted to Native & back, e.g.:
|
|
// k -> {kaf} -> k
|
|
// c -> {kaf} -> k

// Sequences of Latin letters may convert to a single Native letter.

// When this is the case, an apostrophe can be used to indicate separate

// s'h -> {sin}{heh}
