Debug Translation in magento

When you are dealing with multiple translations then some times you want to know the location, from where this translation is coming, so there are steps to debug it:-

1. Go to  app/code/core/Mage/Core/Model/Translate.php

2. Find function translate()

and then write the below code before "return $result":-

$logModule = str_pad($module, 25, "-", STR_PAD_RIGHT);

$logInString = str_pad($text, 150, "-", STR_PAD_RIGHT);

$logOutString = str_pad($result, 200, " ", STR_PAD_RIGHT);

Mage::log($logModule . '>' . $logInString . '>' . $logOutString, null, 'translate.log');

Now check translate.log file under /var/log.

After debugging rollback the whole code in core file "Translate.php"
