Using special characters
If your article contains special characters, accents, or diacritics and you are preparing your manuscript in Microsoft Word, we recommend the following procedure:
For European accents, Greek, Hebrew, or Cyrillic letters, or phonetic symbols: choose Times New Roman font from the dropdown menu in the “Insert symbol” window and insert the character you require.
For Asian languages such as Sanskrit, Korean, Chinese, or Japanese: choose Arial Unicode font from the dropdown menu in the Insert symbol” window and insert the character you require.
For transliterated Arabic: you may choose either Times New Roman or Arial Unicode (unless the Instructions for Authors specify a particular font). For ayns and hamzas choose Arial Unicode font from the dropdown menu in the “Insert symbol” window and then type the Unicode hexes directly into the “Character code” box. Use 02BF for ayn, and 02BE for hamza.
