I have another problem, regarding the
display of Arabic characters - the original mobi book looks good in Kindle for PC (edit: my mistake, the mobi has small characters too), but really bad on my kobo (I changed format to both pdf and epub, still the Arabic names appear too small - see screenshot) Any ideas?
