+## Description
+
+This is a simple c lib that generates a random unicode string of a given length.
+
+## Usage
+
+```c
+#include "library.h"
+#include "stdio.h"
+#include "stdlib.h"
+#include "time.h"
+
+#define BUF_LEN 1024
+
+utf8_t chars[BUF_LEN];
+
+// override the random function to use the system's random number generator
+uint32_t RANDOM_CALL_PROCESS(void) {
+    return rand();
+}
+
+int main() {
+    srand(time(NULL));
+    int len = random_utf8_chars(chars, BUF_LEN, ALPHANUM_AND_CJK_TABLE, ALPHANUM_AND_CJK_TABLE_LEN, 256);
+
+    printf("LEN: %d\n%s\n", len, chars);
+    return 0;
+}
+
+```
+
+```bash
