Emojies are being detected inside a URL string, and in the case of Markdown formatting cannot be bypassed

[shiningwild]

Greetings,
I'm using a Redmine system set to Markdown text formatting.
A Microsoft URL includes characters in the string that are normally for an emoji. Here is an example without any personal information:

https://text.domain.com/:v:/g/personal/persons_email/12345abcd-1234abcd?email=email%40cloud.com&c=123ab

The :v: gets converted to the peace sign hand emoji and results in the following look:

✌️/g/personal/persons_email/12345abcd-1234abcd?email=email%40cloud.com&c=123ab

1. Trying the URL encoding style does not help e.g. (text)[URL]
2. Trying escape slash \ does not help.
3. Trying <pre></pre> tags does not help.
4. Even code highlighting does not help.

We gave up and had to turn off emoji support.

Interestingly, I have tested with Textile text formatting and the fault only occurs with the raw URL. If I use any of the four workarounds I listed above while in Textile formatting the emoji does not appear.

What I have also noticed, in the case of both Textile and Markdown text formatting, the emoji text is detected because it's wrapped with two forward slashes. If I remove either of the forward slashes, the problem does not occur.
What I don't know is what is the meaning of the forward slash?
Naturally, it's expected that emojies should only appear when their is a space before the first : (colon) and a space after the last : (colon).

Thank you for your help.
