Can someone explain the connection between content value, Font Awesome, and Unicode in this context?

Struggling with different character types...

protected void Page_Load(object sender, EventArgs e)
{
    char test = '\uABCD'; //Assigns Unicode character to the variable 'test'
}

But this approach is causing issues:

protected void Page_Load(object sender, EventArgs e)
{        
    char test = '\uEFGH'; 
    // Compiler error: "Too many characters in literal"      
    // However, this value works when used in CSS content attribute.
}

How can I assign the latter value to the test variable? Is it because one is a unicode value and the other is not?

Answer №1

From my understanding, the \f character represents form-feed, and adding a suffix to it goes beyond the limitations of a single character literal.

Answer №2

\u represents a unicode character in C#. This notation consists of the \u followed by a hexadecimal value, as explained further at this link

The first code snippet compiles successfully because it specifies one character, while the second code snippet fails to compile due to having 4 characters - the \f escape sequence and three zeroes.
