js设置编码方式为utf8

fetch('https://example.com/api/data', {
    method: 'GET',
    headers: {
        'Content-Type': 'application/json; charset=utf-8'
    }
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));

const fs = require('fs');

fs.readFile('example.txt', 'utf8', (err, data) => {
    if (err) {
        console.error('Error reading file:', err);
        return;
    }
    console.log(data);
});

const jschardet = require('jschardet');
const fs = require('fs');

fs.readFile('example.txt', (err, data) => {
    if (err) {
        console.error('Error reading file:', err);
        return;
    }
    const detected = jschardet.detect(data);
    console.log('Detected encoding:', detected.encoding);
    const text = data.toString(detected.encoding);
    console.log(text);
});
