Description: ------------ There is a regular expression to check lines for whitespaces in Squiz_Sniffs_WhiteSpace_SuperfluousWhitespaceSniff on line 200. With unicode cyrillic characters it doesn't work and should be this: '|^.*\s+$|u'

Are you able to provide me with some sample code that fails so I can write a unit test for it?

Sure. The test PHP code: <?php function arrayWalkCallback() { // … some business logic // ?????? ?? ????????? ??????? ??? ????? ?????????? ?? ??????? $serviceKeys = ['re', 'hot', 'color', 'up', 'torg', 'wphoto', 'hasphoto', 'auto_re', 'uuid']; // … other business logic } That's how I run PHP_CodeSniffer: $ php vendor/bin/phpcs --standard=PSR2 --encoding=utf-8 test.php FILE: /Users/endeveit/projects/temp/test.php -------------------------------------------------------------------------------- FOUND 1 ERROR(S) AFFECTING 1 LINE(S) -------------------------------------------------------------------------------- 6 | ERROR | Whitespace found at end of line --------------------------------------------------------------------------------

Pear has corrupted unicode. Here is the code on GitHub Gist https://gist.github.com/endeveit/8779468

Thanks a lot for providing that code. I had already fixed this in the phpcs-fixer branch while doing automated fixes for end of line whitespace. At the time, I removed the regex all together as rtrim() worked well for this case. So I applied the same fix for master: https://github.com/squizlabs/PHP_CodeSniffer/commit/7a976e003d7c812f00b03866d3 3dfc32530cd3c3

Thank you
