Dont know if it is possible. Have you ever seen a jpg file with an exif info with cyrillic chars? If so then please put it on the internet and give an url to it. — greenapps, Apr 26 '17 at 09:28
How do you check the result? With your app or an external app? — greenapps, Apr 26 '17 at 09:30
I checked the result in my application and external application. — user1854307, Apr 26 '17 at 09:33
Please define your charSequence variable in your post with cyrillic content. — greenapps, Apr 26 '17 at 09:34
Can you use chars that do NOT look like latin ones? A decent text please! Like: This is me on de Wolga river. — greenapps, Apr 26 '17 at 09:39
Wrong translation! Now i'm waiting for an url. You know that. — greenapps, Apr 26 '17 at 09:47
I specified the Russian alphabet as an example of the initialization of charSequence. — user1854307, Apr 26 '17 at 09:49

Think that ExifInterface class does not support this cyrillic.

I tried to get the bytes from that tag with

    byte [] bytes1 = exifInterface.getAttribute("UserComment").getBytes();
    byte [] bytes2 = exifInterface.getAttribute("UserComment").getBytes("utf-8");
//  byte [] bytes3 = exifInterface.getAttribute("UserComment").getBytes("utf-16");
//  byte [] bytes3 = exifInterface.getAttribute("UserComment").getBytes("ISO-8859-1");
    byte [] bytes3 = exifInterface.getAttribute("UserComment").getBytes("windows-1252");

And then displayed the bytes in hexadecimal notation. They were all rubbish.

There were 66 bytes for your 33 characters. Dont know which encoding is used.

I wanted to compare them with the bytes of your alphabet string.

Also tried compiling for Andoid 7 but all the same.

I give up ;-).

No. If i cannot read the exif then i will not try to write an exif. How would i check the write? Only with external app. — greenapps, Apr 26 '17 at 13:04
Try a different exif interface class. There is. Google for it. — greenapps, Apr 27 '17 at 08:08

"UserComment" tag in Exif support ASCII or Unicode.

Unfortunately, Android's ExifInterface only use ASCII to write or read the tag.

So, cyrillic symbol is not support by Android's ExifInterface.

But this lib may help you:
