# Unicode Support
|
|
|
|
There are three Unicode keymap definition method available in QMK:
|
|
|
|
## UNICODE_ENABLE
|
|
|
|
Supports Unicode input up to 0xFFFF. The keycode function is `UC(n)` in
|
|
keymap file, where *n* is a 4 digit hexadecimal.
|
|
|
|
## UNICODEMAP_ENABLE
|
|
|
|
Supports Unicode up to 0xFFFFFFFF. You need to maintain a separate mapping
|
|
table `const uint32_t PROGMEM unicode_map[] = {...}` in your keymap file.
|
|
The keycode function is `X(n)` where *n* is the array index of the mapping
|
|
table.
|
|
|
|
## UCIS_ENABLE
|
|
|
|
TBD
|

Unicode input in QMK works by inputing a sequence of characters to the OS,
|
|
sort of like macro. Unfortunately, each OS has different ideas on how Unicode is input.
|
|
|
|
This is the current list of Unicode input method in QMK:
|
|
|
|
* UC_OSX: MacOS Unicode Hex Input support. Works only up to 0xFFFF. Disabled by default. To enable: go to System Preferences -> Keyboard -> Input Sources, and enable Unicode Hex.
|
|
* UC_OSX_RALT: Same as UC_OSX, but sends the Right Alt key for unicode input
|
|
* UC_LNX: Unicode input method under Linux. Works up to 0xFFFFF. Should work almost anywhere on ibus enabled distros. Without ibus, this works under GTK apps, but rarely anywhere else.
|
|
* UC_WIN: (not recommended) Windows built-in Unicode input. To enable: create registry key under `HKEY_CURRENT_USER\Control Panel\Input Method\EnableHexNumpad` of type `REG_SZ` called `EnableHexNumpad`, set its value to 1, and reboot. This method is not recommended because of reliability and compatibility issue, use WinCompose method below instead.
|
|
* UC_WINC: Windows Unicode input using WinCompose. Requires [WinCompose](https://github.com/samhocevar/wincompose). Works reliably under many (all?) variations of Windows.
|
|
|
|
To type multiple characters for things like (ノಠ痊ಠ)ノ彡┻━┻, you can use `send_unicode_hex_string()` much like `SEND_STRING()` except you would use hex values seperated by spaces.
|
|
For example, the table flip seen above would be `send_unicode_hex_string("0028 30CE 0CA0 75CA 0CA0 0029 30CE 5F61 253B 2501 253B")`
|
|
|
|
There are many ways to get a hex code, but an easy one is [this site](https://r12a.github.io/app-conversion/). Just make sure to convert to hexadecimal, and that is your string.

# Additional Language Support
|
|
|
|
In `quantum/keymap_extras/`, you'll see various language files - these work the same way as the alternative layout ones do. Most are defined by their two letter country/language code followed by an underscore and a 4-letter abbreviation of its name. `FR_UGRV` which will result in a `ù` when using a software-implemented AZERTY layout. It's currently difficult to send such characters in just the firmware.

# International Characters on Windows
|
|
|
|
[AutoHotkey](https://autohotkey.com) allows Windows users to create custom hotkeys among others.
|
|
|
|
The method does not require Unicode support in the keyboard itself but depends instead of AutoHotkey running in the background.
|
|
|
|
First you need to select a modifier combination that is not in use by any of your programs.
|
|
CtrlAltWin is not used very widely and should therefore be perfect for this.
|
|
There is a macro defined for a mod-tab combo `LCAG_T`.
|
|
Add this mod-tab combo to a key on your keyboard, e.g.: `LCAG_T(KC_TAB)`.
|
|
This makes the key behave like a tab key if pressed and released immediately but changes it to the modifier if used with another key.
|
|
|
|
In the default script of AutoHotkey you can define custom hotkeys.
|
|
|
|
<^<!<#a::Send, ä
|
|
<^<!<#<+a::Send, Ä
|
|
|
|
The hotkeys above are for the combination CtrlAltGui and CtrlAltGuiShift plus the letter a.
|
|
AutoHotkey inserts the Text right of `Send, ` when this combination is pressed.
