C - Print an array filled with Unicode-Symbols
I want to print an array(/string), which is filled with unicode (and normal) symbols , for example squares.
Here's my code:
#include <stdio.h>
int main()
{
char array[5];
for (int i = 0; i < 4; i++){
array[i]='u25A1';
}
array[4]='A';
printf("%s", array);
return 0;
}
It just prints " ííííA◊".
Why doesn't it print the squares, and how to fix it?
According to fileformat.info the square's
C/C++/Java source code is "u25A0"
i also tried the square's
UTF-8 (hex), which is "0xE2 0x96 0xA0 (e296a0)"
Neither work.

array[i] = 'u25A1' will not compile correctly in C. You should at least get a compiler warning.
'u25A1' is of type char16_t (two bytes per character), it is not relevant here.
u can be used as a escape sequence in a string literal, to represent Unicode code points below 0x10000. Example:
strcpy(array, u8"u25A0");
printf(array);
Output: ■
Note that u8"u25A0" is stored as 4 bytes (0xE2, 0x96, 0xA0 + null-character) based on UTF8 conversion. It can also be printed as follow (if the console supports UTF8 output):
strcpy(array, "xE2x96xA0");
printf(array);
Output: ■
Moreover the string should be null-terminated, the last character in the string should be zero.
To store UTF8 in bytes, you can assign values as follows:
array[0] = 0xE2;
array[1] = 0x96;
array[2] = 0xA0;
array[3] = '';
If your development environment supports it you can also declare
char array = u8"■";

Other minor: "u8"u25A0" is turned in to 3 bytes" --> 4 bytes (3 + ) as string literals always append a null character.

It depends on your operating system, the version of your operating system, and if the console supports UTF8. I don't know anything about your environment you are using.

@flogg1: maybe you should specify your OS in your question. The Windows console, for example, may need some forced coercing before it does something as wildly far-fetched as defaulting to UTF8...
