title: Ethiopic font returned by 'echo' and 'printf' is not visible
body: <p>Edit:
  when I use something like </p>
  
  <pre><code>   echo 'coming up is ethiopic font: እናመሰግናለን';
  </code></pre>
  
  <p>It works fine
  but when there is some ethiopic string returned by function as shown below, the returned string is not visible. </p>
  
  <pre><code>      echo 'coming up is ethiopic font:'.my_string();
  </code></pre>
  
  <p>when my_string() returns some ethiopic font, that part will not be visible.</p>
  
  <p>Is there any global setting with PHP? or what can I do ?</p>
  
  <p>As you can see at the footer of the page at <a href="http://ethiopianlanguages.com/ethiopian-calendar/" rel="nofollow">here</a> the font is partially visible(it is visible at least if you have the fonts on your pc).</p>
  
  <p>The problem apeared on my host server, but no problem on my local server</p>
  
  <p>EDIT:
  My problem seems something different from the php functions. I tried relocating the code from the side bar to the header section, and the same code works fine in the header section, but not in the sidebar. Therefore, I am suspecting something else. I added CSS and HTML tags to the question.
  Thank you.</p>
