iOS 15.4 fixed regular spaces ( ). However, non-breaking spaces (\u00A0) may still render inconsistently in web views. Workaround: Use regular spaces and set the paragraph style to monospaced.

Since iOS 15.4, the “space font download” issue has not recurred. Apple added better logging for font registration in iOS 16 and 17, and developers now have clearer APIs to check if a font is truly active.

The result? Alignment columns in code editors would shatter, ASCII art would look like abstract modern art, and coding notes would become unreadable.
