Problems with Lightroom cloud metadata charset/language

Well, its really simple. It has affected all my Lightroom cloud images since I started using it. I even tried with support to create a totally new account which seemed to help with new test images. Then Adobe transferred all the old files to the new subscription. And the problem came back in the new subscription. I dont know if its in the user profile data wrong, or after the old pictures were restored to the new account it somehow corrupted something back.

What happens is when image is imported to lightroom (either from my iphone with the app on the phone, or from canon dslr memory card), it saves the location metadata into IPTC core fields: City, State/Province, Country in wrong locale/language, in this case thai text. Which is really strange as I dont remember using Lightroom on my Thai vacation a long time ago. Also the problem is the same in both Windows and Mac lightroom cloud apps. On Lightroom Classic there is no problem, the language is correct for these fields. So the problem/bug is somewhere in the Lightroom/Adobe Cloud.

I have discussed about this with support several times, shown it lately to two support persons with all the detail and examples. But never since I have shown it has there been any fixes or progress, first time I opened a ticket on this was december last year. One of the latter support specialists told me after very thorough testing that she is going to send it to product development, to be never heard of again.  And the same with another one with whom we also checked the iphone/windows/mac and once the problem was verified the support person just vanished!!

I have also asked many support people to open a problem ticket, and have it transferred to a problem manager so this issue would finally be inspected and handled properly. I dont understand how can it be this difficult in Adobe to fix this after showing it and not even receiving any updates.

I have shown this how it happens, the metadata fields in bridge, several people have checked all my settings and we have reset the apps and settings multiple times with no help. The problem is somewhere "in the cloud". 

If I only use my iphone/mac/windows on lightroom classic everything is fine., metadata in lightroom classic (which I dont use and dont want to use is fine)  Lightroom cloud breaks the metadata language somehow the second I import an image to lightroom cloud.

Since you are an adobe employee, how are problems like this handled and managed? Of course now I have thousands of images, all with wrong language metadata in lightroom cloud that should be fixed also. And all the pics I edit with lightroom have corrupted metadata in wrong locale (thai). If I copy paste the text to google translate, it shows that the text is right and fine, just wrong character set, which lightroom cloud brings for some odd reason.

Do you have a problem management process/people to fix things like this, or how can we proceed with it? 1st and 2nd level support dont seem to be able to help, or support people who know what they are doing and have 8 years of experience solving difficult problems. And I hope you wont disappear as well now when I have taken all this time to explain it.. Here is a screenshot from Adobe Bridge showing the problem.
