Hi @DOOKINO,
I recognize how frustrating this situation can be, and I would like to look into it more closely. Could you please provide the exact version of Illustrator you are using, along with the details of your operating system? Moreover, a short screen recording that shows the issue when converting the Georgian text to uppercase would be very helpful. It would also be useful to know the source of the font, whether it comes from Adobe Fonts or another provider. If you can, please share the link to the foundry or the font file itself, so I can test it on my side and investigate this issue. You can use any public cloud sharing services like Drive, Dropbox, etc., to share the font file. If it’s sensitive, feel free to send it via DM.
Additionally, please let me know if the issue occurs in every new file or just in a specific document.
I am eager to hear back from you so I can provide further assistance.
