typing the underscore symbol to remote Windows OS would turn into a hyphen

[perl168]

I use Teamviewer on Android phone (Galaxy Note Edge) and notice that whatever Android keyboard I use, typing the underscore symbol would turn into a hyphen in the remote Windows OS, whereas it remains correct as an underscore in the remote Mac OS X. So, this is a problem only for Android->Windows. Does anyone have the same problem? Is there a solution? I have to type the underscore a lot for my use. Thank you.
