1. Open a page in VE
2. Create a new heading or preformatted with the text "Foo"
3. Type the text "Bar" into the search bar, select it, and copy it (Ctrl+C)
4. Place the cursor at the (beginning|middle|end) of Foo
5. Press Ctrl+Shift+V
6. See breakage and funny Unicode characters

The result depends on step 3: pasting at the beginning will create a new paragraph with "Bar☂" before it; pasting at the end will create a new paragraph with "☀Bar" after it; and pasting in the middle will split the heading/preformatted and create a paragraph with "☀bar☂" in between the two. However, if you use a paragraph in step 2, then you will get the correct result ("BarFoo, "FooBar" or "FoBaro").
