strwidth(s)

Gives the number of columns needed to print a string.

The strwidth function in Julia returns the number of columns needed to print a string. It considers the width of each character, including special characters, emojis, and multi-byte characters.

Example usages:

Count the number of columns for a simple string:
```
julia> strwidth("Hello, Julia!")
13
```
The string "Hello, Julia!" requires 13 columns to print.
Calculate the width of a string with non-Latin characters:
```
julia> strwidth("こんにちは、ジュリア！")
15
```
The Japanese string "こんにちは、ジュリア！" requires 15 columns for printing.
Determine the width of a string with spaces and special characters:
```
julia> strwidth("Julia is awesome!")
17
```
The string "Julia is awesome!" requires 17 columns to print.

Note: strwidth considers the display width, which may differ from the actual number of characters in the string due to variable character widths.
