Here is a sample of the Chinese text. It has a button to click to toggle showing the text and the htmlText in the same fields. Note to see the text problems you will have to open this in Windows 10. I must point out that the LC 8 versions only show the anti-alias rendering problem in Chinese MS Windows installations!
LC 9.0: Bold and not bold-looking rendered text mixed in together. It should be NOT bold. LC 8.1.9:Shows bitmap glyphs in standard Windows OS. However it renders text as anti-aliased but poorly in Chinese MS Windows installations LC 8.1.3 Shows bitmap glyphs in standard Windows OS. However it renders text as anti-aliased but poorly in Chinese MS Windows installations https://artsinteractive-products.s3.amazonaws.com/MITA/Chinese%20Display%20Sample.livecode pb > On Aug 13, 2018, at 1:11 PM, Peter Bogdanoff via use-livecode > <use-livecode@lists.runrev.com> wrote: > > Thanks Mark for your reply. > >> >> Heh - well I can't explain the difference between 8.1.3 and 8.1.9 - there's >> no changes to libgraphics or libskia between those two versions (as far as I >> can see) also with a quick diff of the relevant source files I can't see any >> relevant field changes, or image changes (which would be the cause of the >> vertical stretching of the inline image).
