Game fails to display non-latin alphabet characters possibly due to PR #37668

[VoidForge]

Describe the bug

All non-latin alphabet characters fail to be displayed in build #10316. Likely caused by erroneous code in PR#37668.
I believe that the problem is caused by std::unique_ptr<Font> Font::load_font( const std::string &typeface, int fontsize in src/sdltiles.cpp, where fonts in data/font are not loaded unless an error is thrown during loading of user's font.

   if( ends_with( typeface, ".bmp" ) || ends_with( typeface, ".png" ) ) {
        // Seems to be an image file, not a font.
        // Try to load as bitmap font from user font dir, then from font dir.
        try {
            return std::unique_ptr<Font>( std::make_unique<BitmapFont>( fontwidth, fontheight,
                                          PATH_INFO::fontdir() + typeface ) );
                                          PATH_INFO::user_font() + typeface ) );
        } catch( std::exception &err ) {
            try {
                return std::unique_ptr<Font>( std::make_unique<BitmapFont>( fontwidth, fontheight,
                                              PATH_INFO::fontdir() + typeface ) );
            } catch( std::exception &err ) {
                dbg( D_ERROR ) << "Failed to load " << typeface << ": " << err.what();
                // Continue to load as truetype font
            }
        }

Steps To Reproduce

Download build #10316 and switch to other languages like Russian or Chinese.

Expected behavior

The characters are displayed correctly.

The bug is not observed in build 10316, but present in build 10317, so I am pretty sure that PR No. 37668 Added support for user font directory causes this bug.
