This should only happen if you’re outputting to a terminal, and then  
only as specified in Unicode Standard Annex #11: East Asian Width.  
You’ll want to treat ambiguous characters as narrow (unless you’re  
willing to target non-UTF8 output, but then you’re in for a lot of  
other trouble anyhow).
