Describe the feature When parsing/rendering markdown that contains images, allow the consumer the ability to transform URLs. It's very common for markdown to contain relative URLs such as /public/images/something.jpg however it would be very useful be given a callback allowing us to transform this URL and return a new value.

Why is this feature necessary? There are two use cases, the first being why I created this issue, but I am sure others will also have a need for this.

• This is virtually a requirement when creating RSS feeds. It is known that RSS is a poorly implemented specification, and creating HTML for it is always a difficult process. Some readers will require absolute URLs to render images such as https://www.example.com/public/images/something.jpg while others are happy to work with /public/images/something.jpg.
• Image optimisation and caching. It's very common to take advantage of cloud based image optimisation, CDNs, caching etc. Such as https://cloudinary.com/documentation/media_optimization.

If Marked allows for URLs to be transformed these two use cases would be solved.

Describe alternatives you've considered

• Using Marked to manually walk the AST
  • Powerful but complex for a fairly common task
  • Like to lead to bugs in consumer code
• String search/regex
  • Yuck
• Putting absolute URLs in markdown
  • Not a realistic or feasible option as URLs are going to be different between environments, CMS's that produce markdown don't insert absolute URLs, does not truly solve the problem anyway.

Marked version: 4.2.12 (noticed on 4.0.10, tried upgrading to see if it helps)

Describe the bug Invisible non-breaking space characters, like in this block right here, (inline as code and content)

## h2
### h3
[link](destination)
### anotherh3

## h2 ### h3 link ### anotherh3

are not always treated as whitespace, so things like headers, tables, etc don't get formatted and are left as markdown syntax.

To Reproduce Steps to reproduce the behavior:

1. Marked broken

   marked will create headers for the first few elements but then stop. adding extra newlines OR replacing the nonbreaking space characters seems to fix it?

2. CommonMark broken worse

   commonmark doesn't create them at all, you have to replace the nonbreaking spaces

3. DaringFireball's site seems to do "best", the headers are properly replaced AND the nonbreaking space stays intact?

Expected behavior Best, I'd expect all the headers to be generated, keeping the nonbreaking space intact and without extra newlines/spacing (we're moving from one platform to another and have a ton of existing and customer markdown content that we don't control and can't convert).

Marked version: 4.x Ancient code on marked 0.7.0 seems to handle this better

Describe the bug A table with mismatched headers and rows won't render:

| One header |
|:------------- |:-------------|:-----|
| row | has | 3 cols |

We have a site using an ancient verison of marked, ~0.7.0, where this works in a strange way, which generates this:

<table>
<thead>
<tr>
<th style="text-align: left;">One header</th>
</tr>
</thead>
<tbody>
<tr>
<td style="text-align: left;">row</td>
<td style="text-align: left;">has</td>
<td style="text-align: left;">3 cols</td>
</tr>
</tbody>
</table>

To Reproduce Steps to reproduce the behavior:

1. Marked broken example if you add a couple | to the first line to have matching number of columns, the table will start working
2. CommonMark, DaringFireball don't support tables

Expected behavior The ancient behavior of creating a table with a partial header was much more forgiving. In this case, the second header line specifying the alignment is correct and i'd expect that to be the thing that "wins".

Marked version: master

Expected behavior Chinese colon be parsed fine.

add type definition (#286)

I haven't used vite but I wonder if it is using the umd script. The umd script adds window.markedEmoji as a global variable. see if that works.

If you could create a repo where I could reproduce this I could help debug it.

See https://github.com/express-handlebars/express-handlebars#extnamehandlebars

I think 'handlebars' needs to change to '.hbs'

Looks like you are using v3.0.0 toSVG was added in v4.1.0
