"Double quotes" are not displayed properly : Even in Fresh Installation

I noticed this strange bug on Ubuntu. When I open a terminal and select -> Edit-> Profile Preferences, I get the window as shown below ☟ . The double quotes are not being displayed properly, and I do not know why. Please help me to solve this bug.

EDIT:

• out put of echo $LANG : en_IN
• During The installation, I connect to internet and set my location to Bangalore-ಬೆಂಗಳೂರು (India)

UPDATE :

I noticed something even more weird, This happens to all the windows with " ", but NOT in FULL SCREEN Mode

But when the same window is made fullscreen :

Most Important:

• YES!, This Error Exists even in all the Virtual-Machines(Ubuntu) in Virtual-box (both host and VM)

• NO! This error does not happen when I boot from a LIVE-USB (Ubuntu)

No Luck with Fresh Installation:

With no other Options Left, I Completely removed my current 14.04 Ubuntu, Formatted my Hard disk and Installed Ubuntu 15.10 , Installed Nothing on it - First thing I did is Check this Error. YES! But quite different this time

Solution 1:

This minor issue appears due to your regional language settings. When you switch the regional settings to English (United States), the double quotes are displayed correctly after logging out and back in. During the installation process you selected Bangalore as your location. That is the reason why it is displayed in the wrong way. You have to decide what is more important for you, living with this little minor issue and having your regional settings including the Indian currency set in the correct way, or having set and using the foreign language English as default language.

You may want to consider to file a bug report on Launchpad for getting this solved in the future editions of Ubuntu. Maybe other users are annoyed about this issue as well and confirm the bug.
