why tamil characters are not printed properly?

Question

I found a program online and just modified it a little, but the tamil characters are not printed properly. when i give a compile time input senetence in the pgm itself, it prints the characters properly into the new file. But when i give a file as an input, it does not print it properly. the vowel mathras are printed separately. how do i solve this?

Input : sentence given in the pgm itself

   #!usr/bin/python
   # -*- coding:UTF-8 -*-
   import codecs,os
   import tamil.utf8 as utf8
   with codecs.open('singl','w',encoding='utf-8') as ff:
        letters = utf8.get_letters(u"கூவிளம் என்பது என்ன சீர்")
        for letter in letters:
            ff.write(unicode(letter))
            print unicode(letter)
            ff.write('\n')
   ff.close()

output: கூ வி ள ம் எ ன் ப து எ ன் ன சீ ர்

Input: From a File

   #!usr/bin/python
   # -*- coding:UTF-8 -*-
   import codecs,os
   import tamil.utf8 as utf8
   with codecs.open('syll','r',encoding='utf-8') as f:
   with codecs.open('singl','w',encoding='utf-8') as ff:
    for line in f.read():
        letters = utf8.get_letters(line)
        for letter in letters:
            ff.write(unicode(letter))
            print unicode(letter)
            ff.write('\n')
   ff.close()
   f.close()

output: அ ற ு ப த ு க ள ை
