# The Text Variable Data Type

## Text

The text variable data type is used to represent just that, text. You'll find many uses for the text type including displaying text in a Label, capturing data from users such as their phone number or email address, or representing data types that do not exist such as a color.

A String literal can be entered into an Airscript expression by enclosing the text inside double quotes. For example to create a text variable containing the string "The quick brown fox" one would write the Airscript expression as
"The quick brown fox"
There are times when one might want to embed dynamic content inside a text variable.
Text variable literals support embedding the result of an arbitrary Airscript expression by enclosing the expression inside {{ and }}. This is called Text Interpolation. For example, if one has a variable named count that contains a Number one can embed the value of that variable like so:
"The count is: \{{FORMAT_NUMBER(count, "#")}}"
In order to create a text literal that contains a double quote, '"' it is necessary to escape the double quote by preceding it with a backslash '\'. For example:
"\"Airkit is the coolest\" said Mary."
This is needed to differentiate a double quote that should be a part of the Text content vs a double quote that marks the end of the string. In addition to \" Airscript supports the following additional escape sequences.

 Escape Output \" A double quote character '"' \\ A backslash character '\' \n A newline \r A carriage return \v A vertical tab \t A horizontal tab \b A backspace \f A form feed \{{ The characters '\{{'

Internally, Text is stored as random access sequences of UTF-16 code points. For many characters this means that each character takes up one slot in the string. However, some characters may take two slots. For example the emoji the grinning face emoji '😃' has a length of two rather one.
