Vue-router decodeURI twice cause URL contains encoded % an URIError: URI malformed

See original GitHub issue

Version

3.0.3

Reproduction link

Sorry, It is hard to supply a minimal reproduction

Steps to reproduce

Visit http://a.b.c/#/test?d=%25 Vue-router will throw a warning URIError: URI malformed, and abandon all the query params.

What is expected?

DecodeURI once is enough.

What is actually happening?

DecodeURI twice.

ref: https://github.com/vuejs/vue-router/blob/627027fd4351c1a6fa4926765c805165a56d7818/src/history/hash.js#L100-L106 https://github.com/vuejs/vue-router/blob/627027fd4351c1a6fa4926765c805165a56d7818/src/util/query.js#L37-L63

The getHash method already decoded href, but parseQuery decode it again. So caused URIError: URI malformed. Maybe decoding in getHash is not necessary.

Check #2725

BTW % is not a valid character in a url (per spec). You have to use the escaped version %25
