Hello everyone!
I just started using mp3tag, and find it amazingly efficient! I only had a little issue:
Some of my mp3s have both unicode and iso8859-7 (greek) fields. When I try to convert tags to unicode, the fields that are already in unicode become question marks (I guess the converter treats unicode fields as iso8859-7).
I tried creating a new action, but that chooses all fields, without letting me choose which field to convert. Is there a way to solve this problem? (For example, to be able to code-convert only the ARTIST field for a file...)
I appreciate your help!

Hello vergad,
what codepage did you choose at the convert codepage action?
Best regards,

Hi Florian!
I used greek-1253. It works perfect when the fields are not already in greek...
Thanks for taking care

It's kinda strange that you have a file with some fields stored as Unicode and some fields stored in the system codepage. Normally an application writes all fields in the same format.
I'm sorry, but this action can't be applied to certain fields at the moment.
Best regards,
