• WordPress 6.6.2
• PHP 8.1.29
• BlogText 0.9.10

Steps to reproduce

1. Begin a new post

2. Add the text:

file:///C:/Program%20Files

3. Click "preview" on the right-hand side

A new tab opens, with the message:

403
Forbidden

Access to this resource on the server is denied!

Workaround 1

Replace the colon character : with the Unicode character U+A789 ꞉

file://
=>
file꞉//

Workaround 2

I've seen the above colon replacement not work with this example:

Location: jar:file:///C:/Program%20Files%20(x86)/Mozilla%20Firefox/browser/omni.ja!/chrome/browser/content/browser/aboutNetError.xhtml
=>
Location: jar:file:///C:/Program％20Files%20(x86)/Mozilla%20Firefox/browser/omni.ja!/chrome/browser/content/browser/aboutNetError.xhtml

The solution in this case was replacing the first occurrence of the percent character % with the Unicode character U+FF05 ％
