I was playing with the new "copy all text" feature, and stumbled upon one document where the copied text was truncated; see http://mirrors.ctan.org/info/lshort/english/lshort.pdf
The problem turns out to be that on page 83 the textLayer contains
\u0000
and apparently copying just stops when a null char is encountered. To fix this we can simply use an existing helper function, and with this patch we're able to successfully copy all the text in that document.
