Can't type the @ symbol

[araghon007]

So, I have a relatively weird keyboard layout, where you have to press Ctrl+Alt+V (AltGr+V) to type the @ symbol.

FNA/src/FNAPlatform/SDL2_FNAPlatform.cs

Lines 946 to 952 in 575439a

	else if ((Keyboard.keys.Contains(Keys.LeftControl) || Keyboard.keys.Contains(Keys.RightControl))
	&& key == Keys.V)
	{
	textInputControlDown[6] = true;
	TextInputEXT.OnTextInput(FNAPlatform.TextInputCharacters[6]);
	textInputSuppress = true;
	}

FNA/src/FNAPlatform/SDL2_FNAPlatform.cs

Lines 961 to 965 in 575439a

	else if ((Keyboard.keys.Contains(Keys.LeftControl) || Keyboard.keys.Contains(Keys.RightControl))
	&& key == Keys.V)
	{
	TextInputEXT.OnTextInput(FNAPlatform.TextInputCharacters[6]);
	}

I'm not entirely sure how to fix this properly, but it seems checking if Left Alt and Right Alt aren't pressed does the trick. I know Ctrl+Shift+V pastes normally on Windows, so Alt seems to be the only special key that changes the behavior.

I want to say that the issue could be less about the keys and more about the mod state... I do know we have support in SDL for alt/shift/etc but I don't know if it would be applicable to this situation - ideally we could get an event that explicitly asks for a paste operation, so that we aren't manually checking keys like this.

This is wild speculation on my part though; if there's not a graceful way to get the paste request I'd be okay with adding checks for Alt keys being released.

I did see a mention of SDL_CLIPBOARDUPDATE elsewhere emscripten-ports/SDL2#125 (comment)
however the best I could find about that event is that it may be experimental and triggers on.. clipboard update.

Now that I think about it, what's the reason for using textInputSuppress? It's only set when Ctrl+V are pressed, and only used with the SDL_TEXTINPUT event, however pressing Ctrl+V doesn't trigger the text input event on Windows. I'm guessing it's an issue with a different platform then?

I believe so, yes - that's been there for close to 9 years though, so it's been a while since we've really looked at this portion thoroughly 😅

[flibitijibibo]

Correction, it's been almost 10 years!

Oh wow, I've tried following the blame trail, but I didn't know about the archive repo. Also, thanks for the speedy replies.
