Can you try using different fonts and share the results with us.
Sorry I have been away communications, is there a global way to change text as there is a lot of pages of text, titles & captions to change, just as a test?
This does not work in my situation as none of the text is metadata, it a long description of the images & where & why they were taken.
I will be flying out again tomorrow so will not be back for two weeks at that time I will try converting all the text manually. & see if that is successful.
