Here what I am getting

Here what I am getting on my mobile phone

Here is my nodejs code

class ClickatellService {
  constructor() {
    this.sendSms('+mobileNumber', 'このOTPを使用してQuikドライブにログインします。 このOTPを誰とも共有しないでください')
  }

  sendSms(to, message) {
    return new Promise((resolve, reject) => {
      request.get(
        `https://api.clickatell.com/http/sendmsg?user=XXX&password=XXX&api_id=XXX&to=${to}&text=${encodeURI(
          message
        )}`,
        (error, response, body) => {
          if (error) {
            return resolve(error)
          } else {
            return resolve(response)
          }
        }
      )
    })
  }
}

What I can do to be getting the message in simple japanese language.

Any help would be appreciated!!!

Answer 1

You probably need to set the charset to UTF-8 before sending. I don't know what the actual charset your'e using in your code but make sure its UTF-8.

If you already using UTF-8, make sure the actual Font you using is able to handle the Japanese letters.

For more explanation on how to handle Japanese letters, maybe you should check this:

Answer 2

You need to use Unicode to send non GSM characters via SMS and then also set the unicode parameter.

Here is a PHP example:

$converted = iconv(
    "UTF-8", 
    "UCS-2BE", 
    "このOTPを使用してQuikドライブにログインします。 このOTPを誰とも共有しないでください"
);

$sms_data = urlencode(bin2hex($converted));

NOTE: Unicode messages are generally shorter than non-unicode messages, so be careful as you may pay for more than one message, detailed info over here:

Snippet:

70 (16-bit) characters allowed in a single SMS message part 67 (16-bit) characters used per message part when sending concatenated messages
