I tried but it didn't help. From what I understood, CentOS has problems
with unicodes such as 🙊🙉🙈🙆🙆🙅. On that system, it can convert 
any of those characters to wchar_t successfully and properly, but when
we pass that character to iswprint, it returns 0 (considers those wide
characters nonprintable).
