Environment data

• VS Code version: 1.38.1
• Extension version (available under the Extensions sidebar): 2019.9.34911
• OS and version: Ubuntu 19.04, Windows 10

Expected behaviour

CodeLens for skipped tests shows some distinctive mark indicating that this test is skipped.

Actual behaviour

The Unicode symbol used to mark skipped tests is almost not visible on Linux and Windows.

On Mac it shows correctly.

Steps to reproduce:

1. Create a test class with skipped test, for example

import unittest


class AddTests(unittest.TestCase):
    def test_basic_two_plus_one_is_three_passed(self):
        self.assertEqual(3, 2 + 1)

    def test_basic_two_plus_two_is_five_failed(self):
        self.assertEqual(5, 2 + 2)

    @unittest.skip("Skipped for a very important reason")
    def test_basic_two_plus_zero_is_two_skipped(self):
        self.assertEqual(2, 2 + 0)

2. Run all tests
3. Test result mark in CodeLens is not visible for the skipped test.

It looks like that the used Unicode symbol is combining character, see https://en.wikipedia.org/wiki/No_symbol. I can fix this myself and create a PR if this would be ok. But I would like to know what would be the best alternative? I found two - 🛇 and 🚫. This is how they look like

Well, I tried both options on Ubuntu, Windows, and Mac and it looks like the first one (🛇) is not displayed on Mac and the second one looks strange on Windows because it has a white background. I'll try to look for other options.

@kondratyev-nv If you find a symbol that works go ahead and make a PR.
