Originally created by @zerogr4vity on GitHub (Apr 18, 2022).

I am using Markdig.Markdown.ToHtml() to display the contents of a .md file on a webpage. If I provide the following sample string, I get the expected output:
Markdig.Markdown.ToHtml("# Text A\nText B\n\n## Text C")
becomes

<h1>Text A</h1>
<p>Text B</p>

<h2>Text C</h2>

However, if I put the following in a markdown file, I get a weird output:
sample.md:

# Text A
Text B

## Text C

becomes

<p># Text A Text B</p>
<h2>Text C</h2>

I get the expected output when I view the file with Markdown Editor VS2022 extension. I also verified that the file contains the proper characters right before calling the method. Any idea what I can do to achieve the correct output?

Do you have the code that you use to load/parse it? Do you have the exact content on the disk? What is used CRLF or LF, a combination of?

The file contains only CRLF endings.

public class ContractAgreement
{
    public byte[] Text { get; set; }
    public override string ToString()
    {
        return Encoding.Default.GetString(Text);
    }
}

ContractAgreements/Details.cshtml:

@using Markdig
@model ContractViewer.Models.ContractAgreement

@{
    ViewData["Title"] = "Details";
}

<h1>Details</h1>
...
<div>
    @Html.Raw(Markdown.ToHtml(Model.ToString()))
</div>
...

Your file has a UTF8 BOM marker "EF BB BF", so it generates garbage at the beginning and it does not get removed by Encoding.Default.GetString, if you e.g a StreamReader from a byte with the detect byte order marks it would work. Not sure why you are using a byte[], but you might want to revisit this.

Closing as it doesn't look like an issue in markdig, but an encoding issue on your side.
