In orgmode, is there a way to set coding system for the tangled file? For example, my default coding system is utf-8, and when I tangle some src blocks sometimes I want the tangled file to use other coding systems like chinese-gbk. It would be perfect if orgmode had a header argument (eg. :file-coding) for this. What I'm trying to do can be demonstrated with following code blocks:
begin_src mylang :file-coding 'chinese-gbk :tangle tangled.txt
begin_src mylang :tangle tangled.txt
When org-babel-tangle is called, the two src blocks should be tangled into one tangled.txt file with chinese-gbk as its coding system. Note that only the first block has the :file-coding argument.
