 The letter G̃/g̃, which is unique to this language, was introduced into the orthography relatively recently during the mid-20th century and there is disagreement over its use.It is not a precomposed character in Unicode, which can cause typographic inconveniences – such as needing to press "delete" twice – or imperfect rendering when using computers and fonts that do not properly support the complex layout feature of glyph composition.Only stressed nasal vowels are written as nasal.
