Modern Paper command doesn't support parsing asian languages or specific symbols (like '?')

I'm using the latest snapshot of cloud and cloud-minecraft.

When I try to add an argument to my command that may contain Chinese characters, the command doesn't work.

In SINGLE mode, StringParser seems to read all contents from the CommandInput. I suspect this issue is related to the platform's CommandManager.

public @NonNull ArgumentParseResult<String> parse(final @NonNull CommandContext<C> commandContext, final @NonNull CommandInput commandInput) {
    if (this.stringMode == StringParser.StringMode.SINGLE) {
        return ArgumentParseResult.success(commandInput.readString());
    } else {
        return this.stringMode == StringParser.StringMode.QUOTED ? this.parseQuoted(commandContext, commandInput) : this.parseGreedy(commandInput);
    }
}

When I switch to LegacyPaperCommandManager and register a legacy Paper brigadier, the command works correctly.

lateinit var commandManager: LegacyPaperCommandManager<CommandSender>
commandManager = LegacyPaperCommandManager.createNative(this, ExecutionCoordinator.asyncCoordinator())
commandManager.registerLegacyPaperBrigadier()

Here is how I create my command:

commandManager.commandBuilder("home")
    .required("name", StringParser.stringParser())
    .suspendingHandler {
        ...
    }

Legacy brig only appears to work as it does nothing (Paper never re-implemented the old API on 1.20.6+). https://github.com/Mojang/brigadier/blob/master/src/main/java/com/mojang/brigadier/StringReader.java#L169-L175 Mojang is very restrictive on what is allowed in unquoted strings. You must map your argument to a Brigadier type that accepts Chinese characters, like greedy or quoted string.
