调研方向

首先检查为 #1525 修改的实现,并定位用于前景高亮和相同 token 高亮的正则表达式。重现 betáp/betűkkel 情况,然后验证背景高亮仅覆盖完整的 Unicode 标识符,同时保留现有的前景行为。

描述

bug

Hi, Chris,

This is a followup on Issue #1525. That one fixed the colour deviation of Unicode characters in the display of identifiers (red instead of the surrounding black for ASCII).

In the original report I also mentioned the background colour for highlighting all the occurrences of the identifier currently under the cursor. While the foreground colour got fixed in #1525, the identical-token-highlighting (with background colour) did not.

To illustrate: #1525 fixed the token colouring issue, but not the "token highlighting" (of token under cursor) (with light-green background)
example-20210920
(With the cursor on betáp, the expectation would be to highlight all of it, and to not highlight the bet part of betűkkel).

I created this separate issue, because I suspect my comment on the already closed issue might go unnoticed.

I'd totally understand if this would be a a "won't fix" (because of Code Mirror dependency) or low priority, however, I figured given the experience gained with #1525, maybe this turns out to be a similarly minor patch, and someone just has to find the place where the regexes are defined. (I think it's strange to begin with, that the code is not shared with the foreground colour).
