Description

Certain users belonging to a project with an SVN repository get the following exception when performing an Advanced Search for the string svn.

Invalid UTF-8 string passed to phutil_utf8v().

After following the steps described here, I looked at the ssl_error.log to see exactly why this was failing.

I then updated the exception so that I could see the string that was causing the UTF8 string error and found the following:

So the search is working but it's finding a bad character in the SVN repository

Invalid UTF-8 string (rSVN201: Adding M/R processing pipeline dependancies for new Sequence File approach. The\xe2) passed to phutil_utf8v()

That string is a description of an earlier commit to the SVN repository (which is hosted externally to Phabricator).

To make you aware of what was happening. The data was cleaned up on this end but thought there might have been a cleaner way of dealing with a bad character. Because of the cleanup on our end, this is not an issue for us at this point.

Okay, thanks! We'll close this for now and if someone runs into a similar issue we'll look at reconsider options then.
