Incorrect/misleading display of descriptions containing exponents

[elirnm]

Exponents don't display properly in intellisense, hover, etc, so descriptions that have exponents in them display incorrect/misleading values.

Environment

• Operating System: Windows 7
• JDK version: 1.8.0_102
• Visual Studio Code version: 1.9.1
• Java extension version: 0.0.10

Steps To Reproduce

1. Type Integer.MIN_VALUE
2. Notice that both the autocompletion while typing and the tooltip from hovering over the name say that the minimum value of an int is -231 rather than the -2³¹ present in the Java documentation.

Integer.MAX_VALUE does the same thing on hover (231-1 rather than 2³¹-1) but also adds a slash in the autocompletion dialog (231\-1).

So it seems <sup>31</sup> shouldn't be escaped. I believe this is caused by remark:

 Remark passes the HTML to jsoup, to clean up the input text, which strips unsupported HTML tags (the text will remain)

Remark allows Customization of allowed HTML tags - not really recommended., so I can see how this is going

@jrieken @aeschli I tried to return MarkedContent instead of MarkedString, but the sup/sub tags are still not rendered properly. Am I missing something? I thought this would be possible by now.

[Trace - 3:54:26 PM] Received response 'textDocument/hover - (38)' in 29ms.
Result: {
    "contents": {
        "kind": "markdown",
        "value": "Content model element which abstracts attribute declaration from a given grammar (XML Schema, DTD). x<sup>x+1</sup>. x<sub>i+1</sub>"
    }
}

It's markdown, without support for html. You can use unicode variants, like ², or use the 2^32

Might be doable now starting with vscode 1.62:

The new supportHtml property on MarkdownString enables rendering of a safe subset of raw HTML that appears inside the Markdown text.
The supportHtml property defaults to false. When disabled, VS Code will strip out any raw HTML tags that appear in the Markdown text.

New flexmark-java library renders exponents in a slightly better way
