[BUG] - URL parentheses are not URL-encoded/escaped in Markdown links

[oxygen-dioxide]

Affected projects

DocSharp.Docx

Description

When converting a .docx document to Markdown using DocSharp, URLs that contain parentheses (e.g., Wikipedia URLs) are not properly escaped or URL-encoded. This causes the resulting Markdown link syntax to break because the closing parenthesis of the URL prematurely terminates the Markdown link syntax [text](url).

To reproduce

1. Create a Word document (.docx) containing a hyperlink with parentheses, such as https://en.wikipedia.org/wiki/Mole_(unit) (or download docsharp-link-bug.docx )
2. Convert the file using the following C# snippet:

using DocSharp.Docx;
using System;
using System.IO;
using System.Text;

namespace DocSharpExample
{
    internal class Program
    {
        static void Main(string[] args)
        {
            string inputPath = "docsharp-link-bug.docx"; // Path to test file
            var converter = new DocxToMarkdownConverter();
            string markdown = converter.ConvertToString(inputPath);
            Console.WriteLine(markdown);
        }
    }
}

Expected Behavior:

The URL should have its parentheses URL-encoded (( to %28 and ) to %29) so it doesn't break the Markdown syntax.
(For comparison, Python's markitdown handles this correctly):

35.45g/[mol](https://en.wikipedia.org/wiki/Mole_%28unit%29)

Actual Behavior (Bug):

The raw parentheses are preserved inside the link destination, which causes markdown parsers to fail at rendering the link properly:

35.45g/[<u>mol</u>](https://en.wikipedia.org/wiki/Mole_(unit))
