Why 'ARABIC LETTER PEH' is not shown correctly on Android 3.x?

问题

In Unicode characters the ARABIC LETTER PEH INITIAL FORM 'ﭘ' is 0xFB58. When I use the following code to show Unicode characters, everything is OK for every Unicode character in Android 2.2, 2.3. and 4.x But I have problem with ARABIC LETTER PEH 'ﭘ' on Android 3.x and in this case character '~' is shown.

Typeface tf = Typeface.createFromAsset(context.getAssets(),"TAHOMA.TTF");

strChars = "";
strChars += (char) 0xFB58;
tvChars.setTypeface(tf);
tvChars.setText(strChars);

I should mention that The problem is remained when I change the font or ignore using setTypeface(tf)

Why?

How can I find the code of ARABIC LETTER PEH in Unicode?

EDIT:

Please compare 0xFB58 (ﭘ) and 0xFB5E (ﭞ) with any font programmatically. you will find the problem. the first one is not shown but the second one is shown correctly.

Did you try adding your own fonts?

Get a Persian TTF font file that fits you and use it, this way you won't be OS dependent. http://twigstechtips.blogspot.com/2012/01/android-how-to-use-true-type-fonts-ttf.html
