引用在线链接时出现问题

Question

我有一份在线资料可供引用，如下：

@misc{liushort,
    author = "{Liu, Qiang}",
    title = {{A Short Introduction to Kernelized Stein Discrepancy}},
    howpublished = "[Online]. Available from: \url{https://www.cs.utexas.edu/~lqiang/PDF/ksd_short.pdf}",
    note = {Online; accessed 18 March 2021} ,
    year=2016,
}

但是，链接显示不正确。我认为错误出在字符“~”和“_”上。我该如何解决这个问题？
