For example, say we have the following data in the infoset:

<foo>This contains a block end &quote; followed by more text</foo>

And assume that this text is in a block escape with quotes, and a slash escaping the block end character. When unparsed, the above should look like this:

"This contains a block end \" followed by more text"

However, we currently get the following:

"This contains a block end \"ollowed by more text"

So the two characters immediately following the escaped quote are lost (in this example, the space character and the f).
