| | - Tag 0x9286 (6 bytes, string read as undef): However, so long as there are 'non-ASCII' characters in the UserComment field, ExifTools -v3 seems to be not so happy: Then 'æøå' comes up nicely in both apps, as well as in Windows.

TiffFieldTypeConstants.FIELD_TYPE_ASCII, bytes.length, bytes) TiffOutputField exif_comment = new TiffOutputField(TiffConstants.EXIF_TAG_USER_COMMENT, sorry if this becomes a double post - I had some problems with posting this question.īyte bytes = textToSet.getBytes('UTF-8') // 'UTF-8'

So how can that be? I've read on this forum something about it being possible to write non-ASCII characters using 'ANSI encoding'.ĭo you guys know something about such internationalization problems with EXIF data? Maybe you can find some clues in the attached JPEGs? However, in Windows Explorer (right-click > Properties) the Comment in other-app.JPG is shown correctly as 'æøå'. If I run the JPEGs through ExifTool, both seem to have garbled UserComments:Īlso, the two apps can not read each other's encoding (both show nonsense in UserComment when opening the other app's image). I think I'm creating and writing the tag (EXIF_TAG_USER_COMMENT) correctly, but I'm having problems with 'international characters' (i.e non US-ASCII).Īs I've been told, the field has that encoding?Īnyway, here are two JPEGs, where I've written the string 'æøå' using two apps: My app, and ' Photo Exif Editor' (from Google Play). I'm trying to figure out how to write EXIF data (tags) to JPEGs, on Android using the Apache Commons Imaging (Sanselan) library.

Php allow only ascii characters for mac
