HI 

Currently i am using web api for my project. The issue i am facing is sending sms with unicode character inside (Chinese characters). 

In the Cloud API Guide v4.2 - MT API - "Type" parameter wrote : 

"Message Content Type:
“A” – ASCII
“H” – Hexadecimal
“U” – Unicode
It is possible to mix Type A characters and Type U characters within a single message; in this case, you must set Type=U, and treat the message as a Type U message.
Note:
For message with Type U, send the message body as double-byte UTF-16"

and "Message" parameter wrote : 

"Message Content
If Type = “A”, not more than 160 characters
If Type = “H”, not more than (280 – Length of UserHeader field) HEX characters
If Type = “U”, not more than 70 characters".

This is my question: example, i have a message with content like below: 

"Lorem ipsum dolor sit amet, consectetur adipiscing elit 安安安"

1. is it correct if i must convert ALL the content -> UTF-16 then send thought the api ?

2. Type = “U”, not more than 70 characters : this mean the sms in type "U" can send 70 unicode character? example the content have 70 times of  "安" can send ? If this thing can, pls advise. Currently i must convert the mix content like above to UTF-16 like this:  

"004C 006F 0072 0065 006D 0020 0069 0070 ..."

then send.

  Hi there,

  Yes, to send content containing any UTF-16 character, the entire message must be encoded in UTF-16.

  To overcome the 70 character limit, use the 'UserHeader' parameter to send the long message in multiple parts.

  Refer to our Cloud API guide for more details. http://support.commzgate.com/hc/en-us/articles/201875197-Cloud-SMS-API-Guide

  Thank you for quick reply.

  i check on the api again for sure then need the last confirm

  "B- Example for Chinese Message (To send the Character 人)
  ID=1000002
  Password= qrxy53tohh88
  Mobile=6591122334
  Type=U
  Message=4EBA"

  So the length of this sms is 4 (4EBA) or 1 (人) ?

  Hi there,

  '4EBA' constitue 4 characters for Type=U

  Hi there

  Just to be very clear, based on our API for 'Type=U', you can submit 280 hexadecimal characters per request, which will arrive onto your phone as 70 unicode characters.  (Each 4 hexadecimal characters is equivalent to 1 Unicode character)

  Hi,

  Thank, i understand and clear about this. In case you double confirm this. I am checking again my code that why if i send over 180 hexadecimal characters per request then that sms can not go thought. i will come back if i can not find the reason.

  Thank again.
