[IOS]Missing button title

I found a problem
The button title is missing, such as the download button or the button in the About section.
Specifically, the button only displays the fill color without a title

PS:It seems to be due to coding issues...
The codes of different countries are peculiar.

Please show us a screenshot.

What language setting do you use? Perhaps it's an issue with special characters.

Chinese

Although it's not a big problem, it makes people feel uncomfortable visually
