Join link builds unencoded query params (breaks names/rooms with spaces or special chars)

[Jeelislive]

In client/src/components/Join/Join.js, the link to /chat uses raw values for name and room. Special characters or spaces break parsing (query-string) and routing.

Expected behavior

• Query params should be URL-encoded; joining should work with spaces and special chars.

Actual behavior

• Navigation and parsing can fail or produce incorrect values.
