Not really. Note that the internal buffer will not be common to all
pdf_text_t objects, but a different internal buffer in each pdf_text_t
(just as the standard internal buffer containing the UTF-32HE encoded
string). So, if the same object is to be used by different threads, then
the app using the object should provide proper sync mechanisms to access
the object.
