Bug: BitmapText multiline and missing characters

[eXponenta]

Current Behavior

Text is totally corrupts when a Bitmap Font not include all characters needed for text render.

Expected Behavior

Valid text rendering, but with spaces (or any other "unknown" character) as placeholder for missed glyphs.

Like this:

bitmap fonts supported
   1234567890
Woo yay im ubmormal 
bugged this is cool

Steps to Reproduce

Make something like this:

/**
* This is the default playground.
* You should see a bunny spinning in the right preview pane.
* Feel free to use this as a starting point for you own playground!
*/

// Create our application instance
var app = new PIXI.Application({
    width: window.innerWidth,
    height: window.innerHeight,
    backgroundColor: 0x2c3e50
});
document.body.appendChild(app.view);

{
    PIXI.BitmapFont.from("Arial", {
        // no config, use default to emulate missed glyph
    });

    const bitmapFontText = new PIXI.BitmapText(
        ',,,,,,,,,,,bitmap fonts supported ---------  1234567890\nWoo yay im ubmormal bugged,!!!! this is cool!', {
            fontName: 'Arial',
            fontSize: 20,
            maxWidth: 200,
        },
    );

    bitmapFontText.x = 50;
    bitmapFontText.y = 200;

    app.stage.addChild(bitmapFontText);
}

Environment

• pixi.js version: *e.g. 5.1.0 +
• Browser & Version: all
• OS & Version: all
• Running Example: https://www.pixiplayground.com/#/edit/psPB_pby2nbohxf1U6H6V

Possible Solution

No skip character, use DUMMY:

pixijs/packages/text-bitmap/src/BitmapText.ts

Line 282 in 5ae1d3b

continue;

pixijs/packages/text-bitmap/src/BitmapText.ts

Line 316 in 5ae1d3b

utils.removeItems(chars, 1 + lastBreakPos - spacesRemoved, 1 + i - lastBreakPos);

Because after that you use relative index and sure that "i" correspond to char array, but because some chars was drops - indices is shifter every line.
