unicode or something bug in 5.3

hello

I still cant use 5.3 because although charts are working now in 6843 built, thay are still errors.

as you can see if I open a project made in 5.2 most pages are changed ! I spent hours to correctly configure pages in editor so having to reset them is not a possibility.
Then on the web page, as you can see non english words make error

if you could compile a new built that would be nice.

thank you.
