Environment

Windows build number: 10.0.18899.1000
Windows Terminal version: 0.1.1361.0

Steps to reproduce

Setup a standard PowerLine using FiraCode in WSL(2) and navigate to a git repository that contains edits. Note if you
printf '✏' that the pencil is double the size of the one in the Powerline prompt.

image

Expected behavior

I expect emojis in the prompt to appear at the same size as those later in the same line.

Actual behavior

emoji size appears to be halved? See pic.

@DHowett-MSFT commented on GitHub (May 19, 2019):

Fascinating! I think we're doing this technically right, but it doesn't turn out looking right.

According to Unicode, \u270E (LOWER RIGHT PENCIL) is not supposed to be an Emoji. It's not in any of the tables . . . so the real issue here is that we here at Microsoft gave it a glyph and made it one.

This issue may be related to https://github.com/microsoft/terminal/blob/master/src/types/CodepointWidthDetector.cpp. The width obtained by emoji 🛠 (\U0001F6E0) is actually 1.

In this project https://github.com/fumiyas/wcwidth-cjk , the open emoji detection width is 2.

@DHowett-MSFT commented on GitHub (Aug 17, 2019):

It's... slightly more complicated than that. In addition to the table laid out in UCD EastAsianWidth 12.0, which expressly avoids specifying Emoji, there's the Emoji 12.0 table. That specifies which characters are emoji, but we can't just import that table as-is. It specifies a lot of things that aren't emoji as being emoji.

Like this:

0023          ; Emoji                #  1.1  [1] (#️)       number sign

If we ingest this table as is, we'll look even more wrong than we already are.

@DHowett-MSFT After testing, I found that I only need to add an emoji_width table and add the missing emoji symbols to this table to get these emoji widths correctly.

(Some emoji display different widths in different fonts.)

The unicode interval to be supplemented is as follows:

struct interval {
  char32_t first;
  char32_t last;
};
constexpr const interval emoji_width[] = {
      {0x2194, 0x2199},

@JustinGrote commented on GitHub (Nov 19, 2019):

@miniksa So definitely all the ZWJ emojis that force a "character" to an emoji render are affected, as mentioned probably because it's jamming two characters into one width, hence why the emoji comes out small. Spider (U+1F577️ U+FE0F) previously being mentioned as an example.

So detecting a vs16 and adjusting the character width based on the number of following characters would do it, is that part of the #2928 PR?

@JustinGrote commented on GitHub (Nov 22, 2019):

@benc-uk yep, it's because the actual icon is two characters, a "standard" cloud character, and then a ZWJ character which tells the terminal to "force" it to emoji style rather than the character style.

VSCode uses xterm internally and it knows how to interpret that (though it has other spacing issues). Windows Terminal currently only sees it as "one character" in terms of width, so that's why it's half-sized.

@miniksa thanks for your hard work, obviously operational issues trump cosmetic ones :). Its just unfortunate so many emojis are common with another character and use the ZWJ for presentation, so the scope of them are limited, and with more build/test tools using emojis to indicate success, it is more and more of an issue :)

Also seeing tiny emojis, thought it was DPI related but could be related to this issue. ✅⚠️❌🔥 are the emoji's in our test results and devops scripts, so slightly higher priority for us.

I also wanted to give kudos to the engineering and design efforts steering a giant legacy ship while improving terminal and emoji support. To us, as long as VSCode and the new terminal can sort this out, we're all set.

On a side note, it's kinda fun to see the inconsistent emoji behavior on Windows 10 v1909 (released just now). It's like a digital anachronistic circus-show with the legacy terminals thrown in :) .. here is a screenshot for the morbidly curious!

Hey I was linked here from 4747, I made a post back in late April asking if there was a way I could revert the glyph scaling.. I was pretty hopeful when I saw came across the post again

I followed the link above to the store and downloaded the recent version. (I dont know if it helps or not but I am on the win10 slow ring?). nyway things to note:

pros

  • powerline Glyph rendering issues are gone, no longer are the tips of my prompt mismatched.

cons

  • I dont see any diference in terms of scaling.

I bounce between a few monospaced fonts customized with the devicon/font-awesome/powerline font type packages. At first I thouhgt all I had to do was simply find a sweet spot for the glyphs, and believe me I tried to cheat the system with my own font builds before I gave up and moved on.. Anyway I digress,

Some of the BASIC wingdings and things like the check marks, and other glyphss which maintain similar advances to the main font chars dont appear to be affected all that much.

Heres an example of how extreme the scaling can be is:

https://i.imgur.com/nzdWrK9.png.

moved away towards hyper because of the customization it provides and kind of forgot about win term, until the other day. Its actually such a clean experience, my ONLY gripes are the tabs being massive and the font issue and I guess take my fonts pretty seriously so its something I do care about although I know not everyone does... . I can live without full blown UI customizatiions abd what have you but the display gotta be good.

(and for the record, it is super crisp. I REALLY like what has been done)

(just give me my full width glyphs)

So, icon fonts occupy codepoints that are reserved in all versions of Unicode and do not have the "wide glyph" or "emoji presentation" flags set. The best we can do going forward is to render them over two cells (spill) and let the righthand cell destroy the right half of the spillover.

Folks who take fonts seriously should attempt to get those glyph width changes made standard 😉 until then, it's an absolute crapshoot. More info at https://github.com/microsoft/terminal/issues/5095#issuecomment-619186373 (closed).

@meandmymind The default representation for ⚠ is "narrow, single-width, non-emoji". The bug here is that it is yellow (emoji presentation), not that it is small.
