the problem in present in good_name function its check for ascii characters

if (!*name || !((*name >= 'a' && *name <= 'z')
             || (*name >= 'A' && *name <= 'Z')
             || (*name >= '0' && *name <= '9')
             || *name == '_' || *name == '.'))
  return 0;

while (*++name) {
  if (!(  (*name >= 'a' && *name <= 'z')
       || (*name >= 'A' && *name <= 'Z')
                     || (*name >= '0' && *name <= '9')
                     || *name == '_' || *name == '.' || *name == '-'
                     || (*name == '$' && *(name + 1) == '\0')))
   return 0;

but if we input U+0915, it UTF-8 =  E0 A4 95
since E0 it is not valid, 
useradd not adding username saying its invalid username
