+              p In Uartix, strings are sequences of characters enclosed in double quotes (&quot;). Strings are used to represent text and can contain a variety of characters, including letters, numbers, punctuation, and special characters.
+              p Additionally, strings can be concatenated using the + operator and can also be reversed with the ~ unary operator. The multiplication (*) operator can also multiply a string.

+              b(class="pb-2") Escape Sequences 
+              p Escape sequences are used in strings to represent special characters that cannot be directly included in the string. An escape sequence begins with a backslash (\) followed by one or more characters. Uartix supports several escape sequences:
+
+              ul
+                li
+                  b Newline (\n)
+                  p Represents a newline character, which moves the cursor to the beginning of the next line.
+                li
+                  b Carriage Return (\r)
+                  p Represents a carriage return character, which moves the cursor to the beginning of the current line.
+                li
+                  b Tab (\t)
+                  p Represents a tab character, which moves the cursor to the next tab stop.
+                li
+                  b Backspace (\b)
+                  p Represents a backspace character, which moves the cursor one position to the left.
+                li
+                  b Form Feed (\f)
+                  p Represents a form feed character, which moves the cursor to the beginning of the next page.
+                li
+                  b Double Quote (\")
+                  p Represents a double quote character, allowing double quotes to be included within strings.
+                li 
+                  b Backslash (\\)
+                  p Represents a backslash character, allowing backslashes to be included within strings.
+                li
+                  b Unicode (\uXXXX)
+                  p Represents a Unicode character, where XXXX is a four-digit hexadecimal number corresponding to the Unicode code point.
