Camelot scraping issue for Non English (Tamil) PDF

Question

Python Camelot works a charm when it comes to English. But when it comes to Tamil it's not scraping the words properly. It gives more or less junk characters close to the characters I would like to understand what the issue is and how it captures the non-English data.

Work Done So Far: I am trying to scrape data from a PDF from the Tamil Nadu Election Commission. Sample single page data here. For example, the word

is getting scraped as ெபயர்.

Reference: The CSV output just for the first table is attached below

"வ.

Code used for scraping:

# coding: utf8
import camelot

tables = camelot.read_pdf('2.pdf',  encoding='utf-8', pages= '1-end' )

tables
x = tables.n 
print ("No of tables",x)
tables.export('ariyalur.csv', f='csv') 

Addition / Edit for clarity as pointed out by @tripleee For Non Tamil Users. This is the header of the table The Expected output is வ.எண் பெயர்‌ பாலினம்‌ பெயர்‌ கட்சி வாக்குகள்‌ % முடிவு But , the output which has come "வ.எண்.","ெபயர்","பானம்","தந்ைத /கணவர் ெபயர்","கட்ச","ெபற்ற வாக்கள்","சதவதம் %",""
