<pre>DXR (cross ref tool) uses libclang to emit locations (line + col) for symbols
in a file. When the file has any form feed character then the line given by
clang SourceManager is incorrect because it does not consider form feed a line
break.
Note the unicode spec, <a href="http://unicode.org/reports/tr14/#BK">http://unicode.org/reports/tr14/#BK</a>, that defines the
behavior.
>From some initial inspection I think the issue is in
<a href="http://clang.llvm.org/doxygen/SourceManager_8cpp_source.html#l01200">http://clang.llvm.org/doxygen/SourceManager_8cpp_source.html#l01200</a>, which only
considers \r and \n.
For example, see the bug filed at
<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1224516">https://bugzilla.mozilla.org/show_bug.cgi?id=1224516</a>.</pre>
