[BUGFIX] Fix support for non-Latin characters

[ousmorez]

Description

I've added some more characters to the dropdown opener in the regex, so that the dropdown opens when the following keys are pressed on the keyboard:

Because if those characters are available to type, they can open the drop-down menu after pressing.
Also correct first character when trying to type numbers or non-English.

it solves following bug:

#1068

I checked the error in the pipeline and found that the problem is solved if the following packages are installed:

  "pixelmatch": "^5.3.0",
  "puppeteer": "^19.2.2",

We need to add these packages to package.json.
This has nothing to do with my changes, should I add these packages?
