[atoms] Fix getText atom for unicode charater middle of word

[k7z45]

The change to getText atom by commit c065dda
does not handle case when unicode character is in the middle
of a word, and unicode character will be incorrectly capitalized
(see https://bugs.chromium.org/p/chromedriver/issues/detail?id=3611).
The problem is \b mark the boundary between word character and
unicode character as a boundary. This is fixed by explicitly using
unicode flag and specifying unicode character and unicode symbol
in the regex.

Encountered some issues running test locally,
"After I did ./go node:atoms,
then I do bazel run //java/client/test/org/openqa/selenium/environment:appserver
and visit http://localhost:2310/javascript/atoms/test/text_test.html but I still see
test_bootstrap.js:74 GET http://localhost:2310/javascript/deps.js net::ERR_ABORTED 404 (Not Found)"

Hi! Thank you for the contribution! Thank you, also, for pointing out that the run command didn't work for you. The process has changed slightly since the docs were written, and I've recently fixed an issue in the way we set things up. Could you please:

• Rebase on trunk
• Run bazel run //java/client/test/org/openqa/selenium/environment:appserver
• Visit http://localhost:2310/filez/selenium/javascript/atoms/test/text_test.html

It looks your new test cases are failing, but once they pass, I'd be very happy to merge this change in!

Hi, thanks for fixing the test framework!
Do you know why there is a difference in how the text is displayed when I visit the page via
http://localhost:2310/filez/selenium/javascript/atoms/test/text_test.html vs.
file:///path/to/text_test.html?
The texts are totally unexpected in terms of processing the capitalize style.
For example,
äåìî in the hosted page vs.
Äåìî in local file
and
Manipulowanie PrzepłYwem in the hosted page and
Manipulowanie Przepływem in the local file.

I'd suspect that file encodings are to blame. I think the server expects everything to be in UTF-8

[AutomatedTester]

Add <meta charset="utf-8"/> to render it properly

[AutomatedTester]

Also, this patch breaks other tests.

[k7z45]

Thanks, after adding <meta charset="UTF-8">, the text_test.html test passes.
What other tests does it break?

Looks like a merge must have fixed the tests that were failing.

I have merged this PR, thanks for making it work
