Unicode string print - the four faces look different when printing - why?

[treeform]

I can think of several reasons:

  * The fonts are different and the terminal font does not have the proper 
unicode to display that.
  * The terminal does not do the unicode composition thingy needed to display 
the family emoji.
  * The editor saves the unicode in an odd way so that it does not print 
correctly.
  * Nim does not support this unicode.
