I use national characters as diagrams' names. There was message with information about currupted characters. I use also
national characters in objects' names, and there effect was the same (popup with message about corrupted characters).
can you provide more information and scenarios/steps
and more info on the info about corrupted characters
and some gif of what bad characters look like ?
also what os and locale you are running in ?
want to see if this is issue vs enhancement.
I have made a mistake. I had wrong locale selected. I have been using EN locale istead of PL locale. After I changed
locale everything is OK. Sorry for my mistake. I think you can change status of this bug to closed.
