1. Introduction

Vim supports Vietnamese language in the following ways:

Built-in vietnamese-keymap, which allows you to type Vietnamese characters in Insert-mode and search-commands using US keyboard layout.

Localization in Vietnamese. See vietnamese-l10n

2. Vietnamese keymaps

vietnamese-keymap
To switch between languages you can use your system native keyboard switcher, or use one of the Vietnamese keymaps included in the Vim distribution, like below

:set keymap=vietnamese-telex_utf-8

See 'keymap' for more information.

In the latter case, you can type Vietnamese even if you do not have a Vietnamese input method engine (IME) or you want Vim to be independent from a system-wide keyboard settings (when 'imdisable' is set). You can also :map a key to switch between keyboards.

Vim comes with the following Vietnamese keymaps:

vietnamese-telex_utf-8 Telex input method, UTF-8 encoding.

vietnamese-viqr_utf-8 VIQR input method, UTF-8 encoding.

vietnamese-vni_utf-8 VNI input method, UTF-8 encoding.

vietnamese-ime_diff
Since these keymaps were designed to be minimalistic, they do not support all features of the corresponding input methods. The differences are described below:

You can only type each character individually, entering the base letter first and then the diacritics later. For example, to type the word nến using vietnamese-vni_utf-8, you must type ne61n, not nen61 or ne6n1

For characters with more than 1 diacritic, you need to type vowel mark before tone mark. For example, to type ồ using vietnamese-telex_utf-8, you need to type oof, not ofo.

With vietnamese-telex_utf-8, you need to type all uppercase letters to produce uppercase characters with diacritics. For example, Ừ must be typed as UWF.

With vietnamese-telex_utf-8, the escape character \ from VNI is added, hence the confusing ooo input to type oo is removed, which could lead to ambiguities. For example, to type the word Đoòng, you would type DDo\ofng.

Simple Telex (both v1 and v2), including the w[]{} style, is not supported.

Removing diacritics using z in Telex or 0 in VNI and VIQR is not supported.

3. Localization

vietnamese-l10n
Vim messages are also available in Vietnamese. If you wish to see messages in Vietnamese, you can run the command :language with an argument being the name of the Vietnamese locale. For example,

:language vi_VN

:language vi_VN.utf-8

Note that the name of the Vietnamese locale may vary depending on your system. See mbyte-first for details.
