Japanese text not visible in mobile

Question

I am sending text message having Japanese characters.

Here is my message

In japanese

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

Answer 1

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
