Re: [Rd] iconv to UTF-16 encoding produces error due to embedded nulls (write.table with fileEncoding param)

2016-02-22 Thread nos...@altfeld-im.de 
Dear R developers

I think I have found a bug that can be reproduced with two lines of code
and I am very thankful to get your first assessment or feed-back on my
report.

If this is the wrong mailing list or I did something wrong
(e. g. semi "anonymous" email address to protect my privacy and defend
unwanted spam) please let me know since I am new here.

Thank you very much :-)

J. Altfeld

Confirming that there are issues.  I had to rebuild 3.2.3 for Debian (as
the default JDK switched from OpenJDK 7 to 8) and had it just fail on
NEWS.pdf for no clear reason. I was a bit short on time last week because of
travel; I should have reported back here.

R_TEXI2DVICMD=emulation

will enable R to build, including NEWS.pdf and all the vignettes.

We are working on a more complete workaround for R-devel and 3.2.4.
