Why is my email campaign showing as chinese characters?

Why is my email campaign showing as chinese characters?

The Reason: An encoding mismatch between UTF-8 (English) and UTF-16 (Asian languages).
The Cause: Copy/paste directly from Microsoft Word or Outlook into the email campaign editor often includes conflicting formatting codes such as class="MsoNormal" , "font-family:, unsupported non HTML special characters.

Why Chinese?: Standard English text uses 1 byte per character. Asian languages (like Chinese) use 2 or more bytes per character.
If an email program or web browser gets confused by the hidden Microsoft Word code, it might accidentally force the email to read in UTF-16 instead of UTF-8. When this happens, the system mistakenly pairs up every two English letters and reads them as a single Chinese character.

Example: The English letters "h" and "e" get lumped together by the computer as a single 2-byte code, which translates directly into the Chinese character "敨".

How to prevent formatting issues in future campaigns: When drafting campaigns ( this applies to adding marketing text into listings as well) : Never paste directly from Word or Outlook into the Arosoftware text editor. 
  1. Copy your draft, open Notepad (Windows) or TextEdit (Mac in Plain Text mode), and paste it there. This instantly strips away all hidden Microsoft formatting.
  2. Copy your draft, open Notepad (Windows) or TextEdit (Mac in Plain Text mode), and paste it there. This instantly strips away all hidden Microsoft formatting.
  3. Use the built-in Arosoftware text editor tools to apply your bold, alignment, and special characters (like m²).

How to fix this for the recipient who's email is already showing Chinese characters? (Outlook): If an email is displaying this way inside a recipients  Outlook inbox, they can manually force Outlook to read it correctly: ( most other email programs have something similar)
  1. Double-click the email to open it in its own separate window.
  2. In the top ribbon, go to Actions > Other Actions.
  3. Click Encoding and select Unicode (UTF-8). The text will instantly revert back to English.
