Quote:Can anyone tell me how to get byte values of the tag, then decode it with utf-8 to get the exact tag values ?
First, you need to understand that before unicode (DOS era), ascii codes between 128-255 where used for special chars and with pagecodes to handle different charsets.
ASCII Code - The extended ASCII table
One of the reasons TIFF uses this is that TIFF was created before unicode/utf exist, at the time they needed ways to encode non ascii chars.
-So to know what was read, you need to display as hexadecimal.
Your read is probably: 55 6E 69 76 65 72 73 69 74 84 74, ä is usually encoded as 84.
- You need to understand how you data is encoded and then call function that will convert to the coding of your app.
- if you want to update this data, you will need to do a coding in reverse.
In your case, you probably need a conversion from CP437 to urf8.
