charwidth

charwidth(c)

Gives the number of columns needed to print a character.

Examples

Get the width of a single character:
```
julia> charwidth('A')
1
```
This example returns the number of columns needed to print the character 'A'.
Calculate the width of a string:
```
julia> str = "Hello, Julia!";
julia> total_width = sum(charwidth(c) for c in str)
14
```
It calculates the total width needed to print the entire string by summing the widths of individual characters.
Determine the width of a Unicode character:
```
julia> charwidth('🌟')
2
```
This example shows how to get the width of a Unicode character, in this case, the star emoji '🌟'.

Common mistake example:

julia> charwidth("Hello")
ERROR: MethodError: no method matching charwidth(::String)

In this example, the function charwidth is called with a string as an argument. However, the function expects a single character as input, so passing a string will result in a MethodError. Make sure to pass a single character to the charwidth function.
