Object types such as "Text" and "Text Box" are capable of displaying text in other languages, including Chinese. When adding a Text object type, the default font "Arial" may render Chinese text as boxes inside the editor. If the font is set to a Chinese font like 黑體 for example, they should display in the layout correctly.

Even if the font displays as boxes in Construct, if you run a Web Preview or export the project, when testing in browser it should correctly display Chinese for the user assuming user has a standard Chinese typeface installed.
