Although it's not always reproducible, in some environments the attempt to access ezoe::browse ezjscore call will result in no content, in result of a failure to parse as json, an array that includes non properly encoded UFT8 characters.
In these environments, a variation of the patch certified in https://jira.ez.no/browse/EZP-19929, replacing the mb_convert_encoding with a utf8_encode seems to solve the issue perfectly.
Please certify if this patch will not break eZ's stability and functionality
- Load an image with non utf8 content in exif fields into a site
- in an xml block field, attempt to select the image through a insert/edit object or image function
- IF you're affected with the encoding problem, the popup window will be blank
