How can i tackle this input issue

[JIANG-Wu-19]

When I input my username "JIANG-Wu-19" , it goes wrong like this:

This page contains the following errors:
error on line 161 at column 28: EntityRef: expecting ';'
Below is a rendering of the page up to the first error.

The test url is github-readme-activity-graph.vercel.app/graph?username=JIANG-Wu-19
I also test the username "Liwu-di", everything is right.
Do two "-" in my username cause this problem? How can I tackle this issue?
Thank you!

Do two "-" in my username cause this problem? How can I tackle this issue?

It's actually the "&" symbol in your display name J&Ocean at the top of the SVG. In order to have an ampersand in the SVG, you need to use the code &. This is what that would look like encoded in the URL:

https://github-readme-activity-graph.vercel.app/graph?username=JIANG-Wu-19&custom_title=J%26amp;Ocean%27s%20Contribution%20Graph

I hope a solution to this can be found so usernames are properly encoded to work in the graph SVG.
