Consider fullwidth characters when rendering tabs

[amos402]

• VSCode Version:1.10
• OS Version:Windows 10 1607

In vscode, one fullwidth character take one col, so the code is not aligned when import some from the other editors.

Steps to Reproduce:

Examle text

asd = "擦擦擦"		#asd
asd = "あああ"		#asd
asd = "aaa"		#asd

in vscode

in vs

The character count is not equal with the column count

Font rendering is handled by Electron/Chromium. If you'd like to get a wide char rendered with the width of 2 chars, I can recommend trying different fonts. e.g. Inconsolata.

No matter what font used, this problem still exist. The reason they didn't align is not the font, is about the element layout of the editor, you can see the example text will work correctly in other browsers or editors.

👍 I understand now what you refer to, I thought it was about the width of the CJK characters, but it's about the width of tabs following CJK chars.

To the verifier, please use a font where a wide character is painted with the width of 2 latin characters, such as e.g. Inconsolata:

asd = "擦"		#asd
asd = "あ"		#asd
asd = "a"		#asd
