[BUG] non-standard uri fragment

[tekumara]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Toggleterm generates uri fragments that contain #, eg:

term://~/code/typos-lsp//59317:/bin/zsh;#toggleterm#1

This causes LSP servers using a strict URI parser to fail in toggleterm. See tower-lsp-community/tower-lsp-server#65.

Expected Behavior

According to RFC 3986 Section 3.5 the use of # in a fragment like toggleterm#1 is non-standard. Lenient parsers may allow this, but strict URI parsers fail.

To allow interoperability with LSP servers that use strict parsers, would you consider an alternative, for example percent encoding (ie: %23) the # in the fragment?

Steps To Reproduce

Use toggleterm with typos-lsp and notice that it doesn't spell check.

Environment

Anything else?

Thank you!
