finding symbols in textview

Question

I tried a lot of things even tried changing the font of textview but could not get the expected result. Actually, I am just reading a .txt file from my raw folder and then displaying it in the textview. But I am facing a problem when characters like hyphen and ' appear. not everywhere but the textview replaces those characters with ? symbol.

attaching a screenshot of both, the file in notepad as well as textview.

Answer 1

Got the solution to the problem Just converted the file encoding format from ANSI to UTF-8. other formats like big endian and unicode do not work.

Answer 2

you can put your string in an array then compare "?" ASCII code with array cells. get your ASCII number in this link :

Answer 3

Use this method to read the file as UTF-8 otherwise your file might be interrupted (open as ASCII and saved;) :

InputStream inputStream = ctx.getResources().openRawResource(resId);
BufferedReader br = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));
