How to resolve the algorithm Terminal control/Unicode output step by step in the Julia programming language

Table of Contents

Problem Statement

The task is to check that the terminal supports Unicode output, before outputting a Unicode character. If the terminal supports Unicode, then the terminal should output a Unicode delta (U+25b3). If the terminal does not support Unicode, then an appropriate error should be raised. Note that it is permissible to use system configuration data to determine terminal capabilities if the system provides such a facility.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Terminal control/Unicode output step by step in the Julia programming language

The code above is written in Julia and it checks if the output device supports Unicode.

The first line creates a variable c that contains a Unicode character, in this case a black right-pointing triangle.

The second line uses the ismatch function to check if the value of the LANG environment variable contains the string "UTF". If it does, it means that the output device supports Unicode, and the code prints a message saying so, followed by the Unicode character.

Otherwise, the code prints a message saying that the output device does not support Unicode.

Source code in the julia programming language

c = '\u25b3'

if ismatch(r"UTF", get(ENV, "LANG", ""))
    println("This output device supports Unicode: ", c)
else
    println("This output device does not support Unicode.")
end
