Hunspell, an open source spell checker engine has been added to Thunderbird 3 development code replacing previous MySpell engine that currently ships with Thunderbird 2.x and Firefox 2.x.
Hunspell also replaced MySpell as OpenOffice.org’s spell checker last year as it provides some unique and welcomed advantages including support for Asian languages, Unicode support, morphological analysis and support for complex compounds and agglutinative languages like Azeri, Basque, Estonian and Hungarian.
MySpell dictionaries are fully compatible with Hunspell which definitely helps for a very easy transition.
Interestingly, while looking around about Hunspell I found that project Runasimipi is creating a Hunspell Runasimi dictionary to be used with localized versions of Abiword, OpenOffice.org and Firefox at least. This looks as an amazing coincidence for me, as some days ago I was thinking about starting a Runasimi localized Firefox.
Runasimi, better known as Quechua (ketch-wa), is and official language in Peru and the second most spoken after Spanish with about 3 million speakers. An estimated total of 7 million speakers are counted in several other South American countries including Ecuador, Argentina, Bolivia, Colombia, Chile and Brazil.
