Issue Summary

When exporting a Confluence space to HTML, pages containing commas in their titles result in broken internal links. The exporter correctly encodes the comma as %2C in the HTML href attributes, but the browsers require the ‘%' in the ‘file://…’ URL to be double encoded (e.g. the ‘%252C’) within HTML files.

Steps to Reproduce

1. Create a Confluence page with a comma in the title (e.g., Project Status, September).
2. Create a second page that contains a link to the first page.
3. Navigate to Space Settings > Export Space and select HTML.
4. Download and unzip the resulting export.
5. Open the index.html or the second page in a browser.
6. Click the link to the Project Status, September page.

Expected Results

The link should open the corresponding HTML file.

Actual Results

The browser displays a "File Not Found" (404) error.

Workaround

Users must manually rename the files in the export folder within .html files.

macOS

find . -name "*.html" -exec sed -i '' 's/%2C/%252C/g' {} +

Windows PowerShell

Get-ChildItem -Filter "*.html" -Recurse | ForEach-Object {
    (Get-Content $_.FullName) -replace '%2C', '%252C' | Set-Content $_.FullName
}
