Message : Fixed bug 5022 - SDL_iconv_string can get stuck in an infinite loop when encountering invalid characters ciremo6483 In `SDL_iconv_string` the `while (inbytesleft > 0)` loop can end up in a state where it never terminates because the library `iconv` function called from `SDL_iconv` doesn't consume any bytes. This happened when a `WCHAR_T` input string was being converted to `UTF-8` but contained invalid characters. It would first It would first skip a few bytes due to `case SDL_ICONV_EILSEQ` but when there were 3 bytes remaining of `inbytesleft` `iconv` just didn't consume anything more (but didn't throw an error either). It just so happens that the Microsoft Classic IntelliMouse `product_string` contains such invalid characters (`"Microsoft? Classic IntelliMouse?"`), meaning the function would get stuck with said mouse plugged in. A fix for this would be to check if `inbytesleft` was unchanged after an iteration and in that case either decrement the counter like when `SDL_ICONV_EILSEQ` is returned or simply break the loop.

Simple DirectMedia Layer is a cross-platform development library designed
to provide low level access to audio, keyboard, mouse, joystick, and graphics
hardware via OpenGL and Direct3D. It is used by video playback software,
emulators, and popular games including Valve's award winning catalog
and many Humble Bundle games.

More extensive documentation is available in the docs directory, starting
