Transliteration

From KneeQuickie

Transliteration is a scheme for writing a language in a script other than its native script. Many conlangers give their languages a scheme for transliterating their native orthography into the Latin alphabet; see also how to make a good orthography.

Transliteration is most commonly done on the basis of representing each glyph of the native script separately. (This does not necessarily mean that one glyph of the native script corresponds to one Roman letter; many transliterations use digraphs.) However, if the native script uses digraphs to represent single phonemes, it is sometimes preferred to treat them as single units and represent them with one Roman letter or digraph rather than the representations of the separate letters making up the digraph in the native script.
