hi there

I have a file which has a content stream with a lot of BT- ET

In one of the cases it happens so that a Tj operator is not preceded by a
Tf (font selection) operator. In such a case how does PDF understand
what font to apply?
One peculiar thing here is that this happens to the first Tj operator after
BT, there-after all Tj have a corresponding Tf operator to decide the
font. Also the previous Tf before the start of this BT is selecting an
English font and the current Tj (without the Tf operator) is actually a CJK
font stream.

How is PDF understanding this scenario? Is there any way I can find out
if the current text is single byte or double byte data ? Or how can I know
what font to apply to this kind of Tj stream ?

Any help would be appreciated.
