Can you put special characters in a table?-CodePudding

Hello, I'm currently working on a game with a dice system, the overlay is the console. I'm drawing the dice with special characters from here : https://fr.wikipedia.org/wiki/Wikipédia:Caractères_spéciaux/Bordures (sorry it's the french version).

But sometimes, I need to change the look of them. So I created a table (actually multiple, but it's the same problem everywhere), and this table is made of characters. To define what is inside, I put an if/else module, and I just affect characters such as ┃ or ┳ in the cases of the table.

Problem : when I compile the code, I have a warning (-Wall) saying :

warning: overflow in conversion from ‘int’ to ‘char’ changes value from ‘14849195’ to ‘-85’ [-Woverflow]

Long story short, I just want to be able to affect these characters in my table (I tried with normal characters and it worked perfectly fine).

typedef int t_dice[5][2];
typedef char t_diceExtremite[5];
typedef char t_diceMiddle [5][2];

t_dice dice;
t_diceExtremite styleDiceTop,styleDiceBottom;
t_diceMiddle styleDiceMiddle;

for(i=0 ; i<5 ; i  ){
    if(dice[i][1]==1){
        styleDiceTop[i] = '┳';
        styleDiceMiddle[i][0] = '┣';
        styleDiceMiddle[i][1] = '┫';
        styleDiceBottom[i] = '┻';
    }else{
        styleDiceTop[i] = '━';
        styleDiceMiddle[i][0] = '┃';
        styleDiceMiddle[i][1] = '┃';
        styleDiceBottom[i] = '━';
    }
}

Note : I already wrote 'int i;', and I filled dice[][] with values earlier.

Example of a warning message (this is the same for every line) :

/home/myname/code/SAE_1.01/yams.c:82:37: warning: multi-character character constant [-Wmultichar]
82 |             styleDiceMiddle[i][0] = '┣';
   |
/home/myname/code/SAE_1.01/yams.c:81:31: warning: overflow in conversion from ‘int’ to ‘char’ changes value from ‘842347315’ to ‘51’ [-Woverflow]

CodePudding user response：

Use wide characters.

i.e.

 typedef char t_diceExtremite[5]; -> typedef w_chart t_diceExtremite[5];

and

styleDiceMiddle[i][0] = '┣'; -> styleDiceMiddle[i][0] = L'┣';
