Despite

"activationEvents": [
	"onLanguage:python",
	"onLanguage:javascript",
	"onLanguage:latex"
],

in package.json, the extension fails to detect \char, \Uchar and ^^... escapes in .tex files.

Adding

"languages": [{
        "id": "latex",
        "extensions": [ ".tex" ],
        "aliases": [ "latex", "LaTeX", "tex", "TeX" ]
}]

did not help.

We should provide information next to the glyph of the short English name given to the codepoint.

This is useful for non-printable characters, control characters and characters for which no font is available with the required glyphs.

Example format:

Null # Non-printable so need description.
  Space # Whitespace, so need description to distinguish between, say, space and thin non-break space
ሴ Ethiopic Syllable See # Description is nice
இ Tamil Letter I # Description is nice
࿚ Tibetan Mark Trailing Mchan Rtags # No font available for rare character
傷 Ideograph wound, injury; fall ill from CJK # Description is nice
࿚ Cat Face with Tears of Joy # No font found

Hovering over

"\u0023"

leads to

Number Sign (UnicodeHover)

being rendered. I.e., we make the markdown string via

new vscode.MarkdownString("# Number Sign (UnicodeHover)");

which leads to a title being rendered.

All symbols that control how markdown is displayed need to be escaped.

There is a paucity of data for Unihan (Unified CJK Ideographs) and some things should be improved:

1. The name Unified CJK does not include V for Vietnamese, despite roughly 9,000 ideographs being used in Chữ Nôm (and half of those used only in Chữ Nôm).
2. I personally find it frustrating when (No description) is shown for CJKV that has readings/meanings. Perhaps we can provide an option to show readings (enable per language?) instead of showing nothing at all or in addition to any description.

Currently renaming a json file to .js basically adds this support so it should be easy to fix

As a user of NerdFont glyphs and unicode escape sequences,
I want to see the glyphs for NerdFont codepoints in the hover tooltip
So that I can more easily read Oh-My-Posh templates (for example, see Agnoster in the oh-my-posh repo)

Haskell support is being implemented in branch haskell.

As with other languages, a language support extension that interacts with a language server is required for parsing of source files. In this case, vscode-haskell and haskell-language-server are needed.

Unfortunately, the language extension's hovers appear to blocking ours.

Consider the following test file (src/test/test.hs):

module Main where

import Lib ()

main :: IO ()
{-
 - U+0000 -> Null.
 - U+0020 ->  Space.
 - U+1234 -> ሴ Ethiopic Syllable See.
 - U+0B87 -> இ Tamil Letter I.
 - U+0FDA -> ࿚ Tibetan Mark Trailing Mchan Rtags.
 - U+50B7 -> 傷 Ideograph wound, injury; fall ill from CJK.
 - U+1F639 -> 😹 Cat Face with Tears of Joy.
 - \0000
-}

main =
  putStrLn "\0000"

In Output, under Haskell (UnicodeHover) we can see the below when we hover over putStrLn's argument.

The first and last lines of the log above indicate that vscode-haskell is indeed parsing the files correctly, but appears to be blocking UnicodeHover from adding a hover panel.

The output looks like this:

If we hover over the comment, the UnicodeHover panels do appear, but they are displaced all the way above the start of the comment.

We should get in touch with the vscode-haskell team to figure out how to fix this.

Hello,

It is better if the URL for the Unicode page is changed slightly in the unicodeHoverUtils.js.
The current site symbl.cc or unicode-table.com has a lot of advertising.

I changed it like this and it works very well:

- const externalLink = "https://unicode-table.com/en/" + (codePoint <= MAX_CODE_POINT ? codePoint.toString(16).toUpperCase() : "");
+ const externalLink = "https://compart.com/unicode/u+" + (codePoint <= MAX_CODE_POINT ? codePoint.toString(16).toUpperCase() : "");

Many greetings
Detlef Paschke

Emojis do not display in panel even if, e.g., Apple Color Emoji is installed.

Cf.: http://unicode.org/versions/Unicode13.0.0/

The datafiles will have to change.

It would be nice to have a link to the official page/documentation for a codepoint so users can get additional information if needed.

Super easy to do, apparently. Match using regex below.

/\\u+[a-fA-F\d]{4}/

• Java doesn't support Unicode escapes above the 16 bit range (i.e., escapes that require 5 or more hex digits), and uses surrogate pairs instead. Hence, we need only match exactly 4 hex digits.
• Multiple us are supported. This is for code that has been ASCII-fied so that escape sequences in the original UTF-X encoded files can be indicated (they start with \uu; newly-escaped characters will be \u in the ASCII-converted source).

if option is true

const str = "\u0061\u0062\u0063\u0064\u0065"

hover the \u0061 or other characters in the str

show all string

"abcde"

Although Tangut is extinct and only reconstructed phonologies exist, it would be nice to find a reputable source for phonologies and include them. Currently Tangut characters have unhelpful descriptions:

𗀀 Tangut ideograph L2008-0008 (UnicodeHover)

Desired:

𗀀 Tangut ideograph dow1 (L2008-0008) (UnicodeHover)

Furthermore, we should probably figure out how to better transmit the reference/source for the characters, defined here.

This website Tangut.info provides phonetics for characters from Lǐ Fànwén's books 夏漢字典 (1997 & 2008 eds).

We may be able to request use of the data.
