I am creating a text message in which i need a ® (Registered) symbol. I tried using the %%=char(169)=%% where 169 is the ASCII code for the registered symbol. But by using this I get the response:

there was an error processing your request

Can someone please suggest how to add registered symbol to text message. Also please advise if I can superscript the registered symbol.

Working Version:

Thank you for your request. Here is a link to download the XXX Mobile App.%%=char(10)=%%
iOS: http://apple.co/XXX%%=char(10)=%%
Android: http://xxx/xxx

Not Working Version:

SET @Reg = Char(174)
SET @message = Concat("Thank you for your request. Here is a link to download the XXX",@Reg)
%%=v(@message)=%% Mobile App.%%=char(10)=%%
iOS: http://apple.co/XXX%%=char(10)=%%
Android: http://xxx/xxx

I have come across this situation before where MobileConnect Outbound SMS wouldn't respect the spaces and I guess your reg trademark is related to same issue.

The workaround this is by using the ASCII characters within the SMS. Here is the table of the ASCII characters.

Also I'd use the AMPscript Char that returns the ASCII character specified by the ASCII character code in the first parameter.


SET @Reg = Char(174)

SET @message = Concat("This is a sample SMS to check the registered symbol.",@Reg)

Note: Superscript is part of the html tag and is not supported in SMS format.

Here is the screenshot enter image description here

  • Above solution does not work. i get the same error message response. Nov 14, 2017 at 19:00
  • @kunal I have test this myself in MobileConnect and I didn't face any issue. Could you please explain more on how you're testing the SMS? Nov 15, 2017 at 21:00
  • i am sending the keyword to the short code and getting an a reply 'there was an error processing your request'. When i remove the registered trademark from the sms and try again i get the desired message Nov 16, 2017 at 22:29
  • @kunalgidwani Is there any chance you can update your post with the actual code you're using in the sms? Nov 16, 2017 at 22:44
  • Updating the code above Nov 16, 2017 at 22:50

Only some country/code combos support the use of non-GSM characters. Most only support GSM 7 bit alphabet characters - the registered Mark isn't one


According to Marketing Cloud documentation

You can only use GSM 3.38 and UTF-16 characters in SMS message content.

You could try : 0x00AE However if your country/code doesn't support it then you are stuck
