读取中文及UTF-8字符的工具

ReadUnicode是一个读取中文及UTF-8字符的两个函数库。

English Version of README

下载与安装

Github下载：

git clone https://github.com/kiwirafe/readunicode.git

版本v1.0.0

• 支持两个函数，toutf()和tohex()

使用方法

所有函数都在"unicode.h"里面，请在编译时加上unicode.c

toutf()

从UTF-8字符转换为int(从一个文档里读出每个char并把它们转换成Unicode标准的int)

定义

int *toutf(int *arg, size_t M);
//结果必须释放

实战

假设example.txt里面是云台二十八将，孔门七十二贤

#include "unicode.h"
int main() {
    FILE *fp = fopen("example.txt", "r"); //打开example.txt
    if (fp == NULL) {
        puts("Error opening file!\n");
        exit(-1);
    }
    int sentence[100]; //先分配100个空间给读取的char
    int c;
    int counter = 0, i = 0;
    
    while ((c = fgetc(fp)) != EOF){
        sentence[counter] = c; //把读取的char录入sentence里面(c实际上是不完整的Unicode)
        counter += 1;
    }

    int *result = toutf(sentence, counter); //调用函数
    while (result[i] != 0) { //如果不是结束符0
        printf("Unicode %d:\t %d\n", i, result[i]);
        i++;
    }
   
    free(result);
    fclose(fp); 
    return 0;
}

结果：20113 21488 20108 21313 20843 23558 65292 23380 38376 19971 21313 20108 36132

tohex()

从int转换为hex(Unicode标准的标准就是十六进制)

定义

char **tohex(int *quotient, size_t M);
//结果必须释放

实战

#include "unicode.h"
int main() {
    int sentence[3] = {12345, 234567, 1000000}; //假设一个读取完文件的数组
    char **result = tohex(sentence, 3); //调用函数

    for (int i = 0; i < 3; i++) {
        printf("%s\n", result[i]); //打印每个Hex
    }

    free(result); 
    return 0;
}

结果：3039 39447 F4240
