Can be called without `new`.\n *\n * ##### presetName\n *\n * MarkdownIt provides named presets as a convenience to quickly\n * enable/disable active syntax rules and options for common use cases.\n *\n * - [\"commonmark\"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/commonmark.js) -\n * configures parser to strict [CommonMark](http://commonmark.org/) mode.\n * - [default](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/default.js) -\n * similar to GFM, used when no preset name given. Enables all available rules,\n * but still without html, typographer & autolinker.\n * - [\"zero\"](https://github.com/markdown-it/markdown-it/blob/master/lib/presets/zero.js) -\n * all rules disabled. Useful to quickly setup your config via `.enable()`.\n * For example, when you need only `bold` and `italic` markup and nothing else.\n *\n * ##### options:\n *\n * - __html__ - `false`. Set `true` to enable HTML tags in source. Be careful!\n * That's not safe! You may need external sanitizer to protect output from XSS.\n * It's better to extend features via plugins, instead of enabling HTML.\n * - __xhtmlOut__ - `false`. Set `true` to add '/' when closing single tags\n * (`
        `). This is needed only for full CommonMark compatibility. In real\n * world you will need HTML output.\n * - __breaks__ - `false`. Set `true` to convert `\\n` in paragraphs into `
        `.\n * - __langPrefix__ - `language-`. CSS language class prefix for fenced blocks.\n * Can be useful for external highlighters.\n * - __linkify__ - `false`. Set `true` to autoconvert URL-like text to links.\n * - __typographer__ - `false`. Set `true` to enable [some language-neutral\n * replacement](https://github.com/markdown-it/markdown-it/blob/master/lib/rules_core/replacements.js) +\n * quotes beautification (smartquotes).\n * - __quotes__ - `“”‘’`, String or Array. Double + single quotes replacement\n * pairs, when typographer enabled and smartquotes on. For example, you can\n * use `'«»„“'` for Russian, `'„“‚‘'` for German, and\n * `['«\\xA0', '\\xA0»', '‹\\xA0', '\\xA0›']` for French (including nbsp).\n * - __highlight__ - `null`. Highlighter function for fenced code blocks.\n * Highlighter `function (str, lang)` should return escaped HTML. It can also\n * return empty string if the source was not changed and should be escaped\n * externaly. If result starts with `):\n *\n * ```javascript\n * var hljs = require('highlight.js') // https://highlightjs.org/\n *\n * // Actual default values\n * var md = require('markdown-it')({\n * highlight: function (str, lang) {\n * if (lang && hljs.getLanguage(lang)) {\n * try {\n * return '

Because of it, we need to fill all\n * empty elements which should be selectable with elements or characters called \"fillers\". Unfortunately there is no one\n * universal filler, this is why two types are uses:\n *\n * * Block filler is an element which fill block elements, like `

        `. CKEditor uses `
        ` as a block filler during the editing,\n * as browsers do natively. So instead of an empty `

        ` there will be `


        `. The advantage of block filler is that\n * it is transparent for the selection, so when the caret is before the `
        ` and user presses right arrow he will be\n * moved to the next paragraph, not after the `
        `. The disadvantage is that it breaks a block, so it can not be used\n * in the middle of a line of text. The {@link module:engine/view/filler~BR_FILLER `
        ` filler} can be replaced with any other\n * character in the data output, for instance {@link module:engine/view/filler~NBSP_FILLER non-breaking space}.\n *\n * * Inline filler is a filler which does not break a line of text, so it can be used inside the text, for instance in the empty\n * `` surrendered by text: `foobar`, if we want to put the caret there. CKEditor uses a sequence of the zero-width\n * spaces as an {@link module:engine/view/filler~INLINE_FILLER inline filler} having the predetermined\n * {@link module:engine/view/filler~INLINE_FILLER_LENGTH length}. A sequence is used, instead of a single character to\n * avoid treating random zero-width spaces as the inline filler. Disadvantage of the inline filler is that it is not\n * transparent for the selection. The arrow key moves the caret between zero-width spaces characters, so the additional\n * code is needed to handle the caret.\n *\n * Both inline and block fillers are handled by the {@link module:engine/view/renderer~Renderer renderer} and are not present in the\n * view.\n *\n * @module engine/view/filler\n */\n\n/**\n * Non-breaking space filler creator.
