find_by_name, find_by_id have some issues with backslash and single quote chars

appium 1.3.4
python 2.7.6
xcode 6.1.1
ios 8.1 sim

by ID ignores backslash \ chars (forward slash ok)
by Name same behavior

Out[169]: u'abcd'

In [170]: dr.find_element_by_id("ab\cd").text
Out[170]: u'abcd'

In [171]: dr.find_element_by_id("ab\\cd").text
Out[171]: u'abcd'

by ID \\ double backslash at END of string causes problem (double forward slash ok)
by Name same behavior and stack trace

WebDriverException: Message: An error occurred while executing user supplied JavaScript.

by ID ’ single quote char causes problem
by Name has no issue
same error message and stack trace as above

Please post this to the issue tracker so that the appium developers see & fix the problem.

Ok I just realized that this is purely a discussion board. I thought issues had been moved here.
