Describe the bug

In fheroes2, the "File to Save:" window forces a maximum number of characters for the save file name. But if you use the mouse-operated keyboard, there's no such limitation. Personally, I'm in favor of a save file name with "no limit" of characters. :D Related issue: https://github.com/ihhub/fheroes2/issues/1318.

Here is an example of a save file name obtained via the mouse-operated keyboard: Broken_Alliance_00012345678901234567890123456789012345678901234567890123456789012345678901234567890.zip
