Well-known Vietnamese keyboard

Unikey is a keyboard tool solely dedicated to type Vietnamese language characters in Windows. Its core UniKey Vietnamese Input Method engine is most commonly used as the base of many Vietnamese software-based keyboards across different device platforms. On top of that, it's also compatible with the three most popular input methods: TELEX, VNI, and VIQR.

It is a free and open-source program that can be installed on any of your compatible Win32 desktop OS. Furthermore, it has developed its own library which will help you easily integrate this software in various Visual Basic applications.

Supports tons of Vietnamese character sets

From TCVN3 (ABC), VN Unicode, VIQR, VNI, VPS, VISCII, BK HCM1, BK HCM2, Vietware-X, Vietware-F, as well as Unicode UTF-8, and Unicode NCR Decimal/Hexadecimal for web editors — UniKey supports these character sets and encodings. You can possibly define the stated popular input methods as well. To ensure that what you typed in is grammatically correct, you can enable its smart typing and spelling checks feature.

First released for PC, this keyboard tool instantly gained popularity mainly because of its speed, simplicity, and reliability. It doesn't put a strain on system resources and performs on a low amount of CPU and RAM. Up to this date, it's still one of the most well-known programs that can input Vietnamese language characters. This utility is lightweight and portable. It doesn't require installation or an additional library.

You can even run it from a USB flash drive or similar devices and effortlessly use it on other desktops. You will be able to view the Unicode characters for each symbol in the selected font type with ease. Its main windows are pretty straightforward to operate for experienced users. First-time users will probably take some time to fully grasp its operation as its interface is not intuitive.
