When transliterating Arabic text, several other issues may arise. First, some Arabic characters are not specified in the transliteration table, including non-alphabetic characters such as ۞ and ۝, punctuation such as ؛ ؟, and "Hindi" or "Eastern Arabic" numerals. Similarly, sometimes Arabic sentences will borrow non-Arabic letters from Persian, some of which are defined in the full Buckwalter table. Symbols that are not defined in the transliteration table may be deleted, kept as non-Latin symbols embedded in transliterated text, or transliterated into different (non-conflicting) Latin symbols. (For instance, it is straightforward to convert from Hindi numerals to Arabic numerals.) Another issue that arises is how to handle transliterating Arabic text with embedded ASCII text; for instance, an Arabic sentence that refers to "IBM" or an Arabic sentence that includes a quote in English. If the Latin text is not explicitly marked, it is a challenge to distinguish transliterated Arabic from Latin. If transliterated text with embedded Latin is later transliterated back to Arabic, the Latin text will be transliterated into garbage Arabic. Finally, another important decision to make is how much normalization of the Arabic text should be done during transliteration. This may include removing ـ kashida, removing short vowels and/or other diacritics, and/or normalizing spelling.
