How can I show phonetic (IPA) symbols on Android

Question

I am trying to display phonetic symbols in a WebView, but so far I am only getting squares.

For instance, for the word "apostrophe", this should be displayed:

əˈpåstrəfi

but all I am getting on the display is:

□□påstr□fi

If it would help, I am getting the strings from an SQLite database. The string I retrieve has some HTML tags in it, so I use this:

webView.loadDataWithBaseURL("file:///android_asset/", 
     article, "text/html", Encoding.UTF_8.toString(), null);

where I have my CSS files in /assets. And the article variable contains some text enclosed in HTML tags.

I've resolved problem to display phonetic symbols in TextView. The problem is the default android fonts are not implement IPA symbols. I can advise to use ccs like this

@font-face {
  /* Regular */
  font-family: "ConstructiumRegular";
  src: url("http://openfontlibrary.org/content/RebeccaRGB/412/Constructium.ttf") format("truetype");
  font-weight:  400;
  font-style:   normal;
  font-variant: normal;
  font-stretch: normal;
} 

In me case mentioned Constructium.ttf fits.
