How use alt code symbols in a string

 

Hello

When we put an alt code symbol (e.g.   alt+31   ▼) in a string, it shows "?" instead of "▼"

Print("▼");  // won't print ▼
 How can we see characters and symbols properly?
 
Writing to a file will do (unicode mode). Print and PrintFormat don't support wide chars in MT4, but MT5 does.
