If you notice squares showing up in the webpages you visit instead of text, try manually substituting the webpage's encoding. Follow these steps:
1. Click the wrench icon on the browser toolbar.
2. Select Tools.
3. Select Encoding.
4. Pick one of the encodings listed or choose Auto detect. If you choose to auto detect, Google Chrome analyzes the content on the page to recommend the most suitable encoding. For the fastest browsing experience, we recommend turning off the auto detect mode after you leave the webpage.
You can also change the preferred fonts and languages used to load your webpages as per steps given in the link http://www.google.com/support/chrome/bin/answer.py?answer=95416
