Having Â's around means that you probably do not save the file with the correct encoding - or, alternatively, you save it in one encoding, but display on a page with a different encoding. Our suggestion is to check and make sure all is saved with the same encoding.
Please, try the suggestions provided in the following help article:

You can save the ascx file with Unicode encoding using Visual Studio -> File -> Save <PageName> As -> Click on the bottom arrow dropdown button next to the Save button -> choose Save with Encoding -> choose Unicode (UTF-8 with signature).
You have to also set <globalization fileEncoding="UTF-8"/> in your web.config file.
Here are some links that discuss [file] encoding.
