!> Using `UNICODE_SELECTED_MODES` means you don't have to initially set the input mode in `matrix_init_user()` (or a similar function); the Unicode system will do that for you on startup. This has the added benefit of avoiding unnecessary writes to EEPROM.
## `send_unicode_hex_string`
## `send_unicode_string()`
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 separate 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")`
This function is much like `send_string()` but allows you to input UTF-8 characters directly, currently up to code point U+FFFF. Make sure your `keymap.c` is formatted in UTF-8 encoding.
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.
```c
send_unicode_string("(ノಠ痊ಠ)ノ彡┻━┻");
```
## `send_unicode_hex_string()`
Similar to `send_unicode_string()`, but the characters are represented by their code point values in ASCII, separated by spaces. For example, the table flip above would be achieved with:
```c
send_unicode_hex_string("0028 30CE 0CA0 75CA 0CA0 0029 30CE 5F61 253B 2501 253B");
```
An easy way to convert your Unicode string to this format is by using [this site](https://r12a.github.io/app-conversion/), and taking the result in the "Hex/UTF-32" section.
Unlike `send_unicode_string()` this function supports code points up to U+10FFFF.

For instance, typing "`a" will result in à.
