-## `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, and supports all code points (provided the selected input method also supports it). 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.
