Hi, In languages like Ruby or Java (https://docs.oracle.com/javase/7/docs/api/java/lang/Character.html#isAlphabetic(int)), functions to check if a character is alphabetic do that by looking for the 'Alphabetic' property (defined true if it's in one of the L categories, or Nl, or has 'Other_Alphabetic' property). When parsing Tamil text, this works out well for independent vowels and consonants (which are in Lo), and for most dependent signs (which are in Mc or Mn but have the 'Other_Alphabetic' property), but the very common pulli (VIRAMA) is neither in Lo nor has 'Other_Alphabetic', and so leads to concluding any string containing it to be non-alphabetic.
This doesn't make sense to me since the Virama “◌்” as much of an alphabetic character as any of the "Dependent Vowel" characters which have been given the 'Other_Alphabetic' property. Is there a rationale behind this difference, or is it an oversight to be corrected? Cheers, Sundar
