Unikey 4.0 is a input transcript software (open source) for input Vietnamese. Vietnamese use latin word (latin +1). Not like some non english-speak country, they make a keyboard for their language (like azerty, china,japan 102keys...etc), with a limited ressource, vnms use a another cheaper and possiblity way to input: make a transcript-combine software for input (combine key. exemple: a + s = á....). They have officialy some font of VN like VNtime, VNI ... and Unicode (new-international). Unikey is a freeware - one man build, none ad. If you have technical issu with it, you can remove it easily
