Using IME with markdown preview enabled, press ESC/BACKSPACE leads in control characters #37114

timonwong · 2017-10-30T03:48:42Z

VSCode Version: 1.17.2
OS Version: macOS 10.11.6

Steps to Reproduce:

HINT: You may need to enable editor.renderControlCharacters in order to see what happens, or the control characters is invisible.

Open a "markdown preview" in a split (just ensure the markdown preview is visible).
In another split, edit arbitrary file with IME (mine with Chinese Pinyin).
Type some characters using IME, before put them on screen, type backspace/esc to see what happens.

Just see the screenshot for example:

Reproduces without extensions: Yes

The text was updated successfully, but these errors were encountered:

It only happens when you are previewing the markdown content, which means it's caused by the webview.

rebornix · 2017-11-16T00:15:48Z

It turns out that when we preview the md content, the webview will lead to the problem as described in #24981 (you need to double backspace to delete characters). This problem was introduced in Electron 1.5.x, fixed by backporting in 1.6.x, apparently they forgot to backport the fix in 1.7.x. Ideally this can be fixed once we adopt 1.8.x.

In version 1.19.0, this is not the only problem in the markdown file, but all the files will appear.

Proxy305 · 2017-12-27T14:30:09Z

From my observation, this issue only triggers as long as I have more than one editor opened, or have the side bar extended. This issue goes away immediately after the closing all the extra editors AND the sidebar, however reoccurs after the extension of side bar or the opening of extra editors.

More IMEs and file type could be affected. The built-in Japanese IME of macOS is affected, and TeX(.tex) files are also affected.

VSCode version: 1.19.1
macOS version: 10.12.6

gaoliang · 2018-01-22T14:41:59Z

any update?

chenxinlong · 2018-02-09T05:39:29Z

When you push files with these control characters to github, it would be replaced with character " � " like :

In edit mode on github, seems chrome render these characters as a red dot, like :

similar issue here:
if one put an emoji which is longer than 2 byte (for example 🇺🇸, \xe7\xbe\x8e\xe5\x9c\x8b) and hit the backspace, it will left an invisible symbol in the editor (🇺, \xf0\x9f\x87\xba)

malun666 · 2018-04-17T16:29:45Z

Open User Setting, then add "editor.renderControlCharacters": true, . Just, help for show the invisible symbol .

similar mistakes happened in the latex edit scene

+1 same problem

InnerPeace-Wu · 2018-12-02T03:06:04Z

It only happens when you are previewing the markdown content, which means it's caused by the webview.

It seems the problem is triggered by previewing. For latex, I tried to avoid it by setting external pdf viewer.
macos: vscode + skim
windows: vscode + sumatraPDF

@rebornix is there any issue created in the electron repo on the problem on version 2.0.12 ? Or has it been fixed? It seems the original issue electron/electron#9173 has been closed due to unsupported version.

tete1030 · 2018-12-04T06:28:58Z

Sorry, while I can reproduce this issue in v1.8.8, I cannot reproduce it in 2.0.7, 2.0.12, 3.0.10, 4.0.0-beta.8 .
I tested them with Electron Fiddle with the following code using macOS Pinyin input method.
<webview src="data:text/html,<input type=text />"></webview>

I tested in 2.0.12 with Electron Fiddle as suggested by electron/electron#9173 (comment), and the issue seems not reproducible in this Electron version. Am I testing it in a wrong way?

rebornix · 2018-12-04T17:52:51Z

@tete1030 thanks for your help! I already left comment there ;) The trick is only input outside of the webview is running into this weird issue.

YunanChen · 2018-12-06T02:44:17Z

+1 The same problems when using the Chinese input methods and opening the Markdown Preview Enhanced

kouhei · 2018-12-15T17:16:51Z

same problem exists in 1.30.0, but it seems to be fixed in insiders(1.31.0).
IME: MacOS default Japanese IME

same problem exists in 1.30.0, but it seems to be fixed in insiders(1.30.1).

Really? My VSCode still has this problem.

macOS 10.14.1
Chinese IME of Sogou Input
Download insiders edition VSCode (1.31.0-insiders) from the official website

After I typed some word and deleted them, the bug was reproduced.

I tried it again, and then this problem was reproduced.
I was wrong. I'm sorry.

0x4f5da2 · 2019-01-15T07:49:29Z

The same issue can be reproduced on macOS 10.14.2 with default Chinese IME.😅

He2hiwei · 2019-01-20T14:36:31Z

The same issue can be reproduced on macOS 10.14.2 too. It is is so disturbing. When will it be fixed?

rebornix · 2019-01-25T19:08:15Z

@kouhei @0x4f5da2 @He2hiwei do you mind sharing more details about the version of VSCode you are using and steps to reproduce?

Example:

Version 1.31.0-insider (1.31.0-insider)
Commit: 50854c0
macOS 10.14.2
whether you have markdown preview open

The reason I asked for you help on this as I can't reproduce this bug anymore. If the issue is still there someway, I'll look into it and get it fixed. The bug existed for too long and we need to give it an end but I need more info ;)

sanxing-chen · 2019-02-01T03:44:42Z

Hi @rebornix
I'm using 1.31.0-insider with latex-workshop plugin which has a pdf preview webview. And I'm using macOS(10.14.1) default Chinese IME.
The bug cannot be consistently reproduced in 1.31.0-insider, but it still happened from time to time if you input and delete character very quickly.
For LaTeX editing, this bug is pretty annoying, because the ^H in TeX will trigger a compilation termination with errors.

robertying · 2019-02-03T03:37:16Z

It's happening not only in editor but also in VSCode's every input field (I believe).

I used VSCode's built-in Git extension and submitted a commit message in it, and somewhere in my final commit message appears a � on GitHub.

zruijie · 2019-02-28T11:25:31Z

macOS Mojava 10.14.3
vscode 1.31.1 (1.31.1) 1b8e830

Maybe this bug has been fixed. Now I donot meet this bug any more.

MyroshnykRoman · 2019-09-12T06:04:49Z

Issue is still reproduced with Version: 1.38.1
and Japanese IME
