调用JavaScript encodeURIComponent函数

const specialChars = ' !"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~'

for(let char of specialChars) {
  const encoded = encodeURIComponent(char)
  if(encoded != char) {
    console.log(`char: ${char} encoded: ${encoded}`)
  }
}
console.log('~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~')
for(let char of specialChars) {
  const encoded = encodeURIComponent(char)
  if(encoded == char) {
    console.log(`char: ${char} encoded: ${encoded}`)
  }
}
