Description

At develop commit 0750d74cd6ea734e66897876506c78ca12680676, 66 Markdown source files contain 190 link destinations whose entire URL is percent-encoded, for example:

[GitHub](https%3A%2F%2Fgithub.com%2FVisActor%2FVChart)

The deployed HTML preserves this as href="https%3A...". Browsers therefore treat it as a relative path under the current VChart page rather than an external URL. This is visible on the FAQ pages above, where clicking a reference navigates to a path such as /vchart/faq/https%3A....

The intended external URL should be emitted as a normal absolute href. A mechanical decode is not safe for the whole set: 21 of the encoded destinations point at an internal host, so those references need a public destination or an explicit decision to remove them before bulk correction.

I fetched all 4,627 open/closed issues and pull requests and searched their current titles and bodies for https%3A, percent-encoded links, and encoded URLs. The only unrelated match was #2462. The repository has no Discussions; the source history contains only the original documentation imports and no later fix. I found no current owner, linked PR, commit, or duplicate for this link-generation/content problem.

Start by inspecting the 66 Markdown source files containing the 190 percent-encoded destinations, using the FAQ URLs as visible examples. Separate external links from the 21 internal-host destinations before making bulk corrections; done means external URLs render as absolute hrefs and each internal reference has a public destination or an explicit decision to remove it.
