def StringOfAsterisks(myString):
    print(''.ljust(len(myString), '*'))

You might use string methods .rjust() or .center() instead of method 
.ljust().

Maybe you might solve this if you decode your string to unicode.
Example:

|>>> euro = "€"
|>>> len(euro)
|3
|>>> u_euro = euro.decode('utf_8')
|>>> len(u_euro)
|1

Adapt the encoding ('utf_8' in my example) to whatever you use.

Or create the unicode string directly:

|>>> u_euro = u'€'
|>>> len(u_euro)
|1
