Re: [Vala] Printing Unicode Characters

[Emad Al-Bloushi <al3omdah live com>]

Dears,

I have made this sample and I want to post it in GNOME wiki so do you recommend any change ?
void main() {
  
  string unicode_string = "1234567890 ١٢٣٤٥٦٧٨٩۰ ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz 
أبتةثجحخدذرزسشصضطظعغفقكلمنهوي";
  
  for (weak string s = unicode_string; s.get_char ()!=0 ; s = s.next_char ()) {
  
    unichar unicode_character = s.get_char ();
    
    UnicodeType unicode_character_type = unicode_character.type ();
    
    switch (unicode_character_type) {
      
      case unicode_character_type.UPPERCASE_LETTER:
        stderr.printf("'%s' is UPPERCASE_LETTER\n",new StringBuilder().append_unichar(unicode_character).str);
        break;
      
      case unicode_character_type.LOWERCASE_LETTER:
        stderr.printf("'%s' is LOWERCASE_LETTER\n",new StringBuilder().append_unichar(unicode_character).str);
        break;
      
      case unicode_character_type.OTHER_LETTER:
        stderr.printf("'%s' is OTHER_LETTER\n",new StringBuilder().append_unichar(unicode_character).str);
        break;
        
      case unicode_character_type.DECIMAL_NUMBER:
        stderr.printf("'%s' is OTHER_NUMBER\n",new StringBuilder().append_unichar(unicode_character).str);
        break;
      
      case unicode_character_type.SPACE_SEPARATOR:
        stderr.printf("'%s' is SPACE_SEPARATOR\n",new StringBuilder().append_unichar(unicode_character).str);
        break;          
    }                   
  }
}

Best regards,
