incorrect behaviour of api

[demhademha]

the following code allows a user to enter text, which should be presented as braille, using Liblouis dot format. This does not occur however:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <liblouis/liblouis.h>

#define BUF_SIZE 1024

int main() {
    const char* table = "en-ueb-g2.ctb"; // Replace this with the desired Braille table

    char input[BUF_SIZE];

    printf("Enter a string: ");
    fgets(input, BUF_SIZE, stdin);

    // Remove newline character at the end of input
    input[strcspn(input, "\n")] = 0;

    // Allocate buffer for the translated string
    widechar* output = (widechar*)malloc(BUF_SIZE * sizeof(widechar));

    // Initialize input and output length variables
    int inlen = strlen(input);
    int outlen = BUF_SIZE;

    // Translate the input string to Braille
    int result = lou_translateString(table, (const widechar*)input, &inlen, output, &outlen, NULL, NULL,68);

    if (result >= 0) {
        printf("Braille representation: ");
        for (int i = 0; i < outlen; i++) {
            printf("%u ", output[i]); // Print Braille characters
        }
        printf("\n");
    } else {
        printf("Translation failed\n");
    }

    // Free allocated memory for output
    lou_free();

    return 0;
}

Where did you find this information? This is not how the API works. Your input variable should be a widechar*, which is a UCS-2 or UCS-4 encoded string, depending on how Liblouis was compiled. You are casting a char* to a widechar*, that seems fishy.
