A question about the API mkchar()
...g, so only in the English locale could the function work
correctly, under other locale, such as Japanese or Chinese, the string
will be convert incorrectly. As a matter of fact, those utf-8 code
already is Unicode string, and don't need to be converted at all.
I also tried to use the SEXP Rf_mkCharCE(const char *, cetype_t);,
Parsing the CE_UTF8 as the argument of cetype_t, but the result is
worse. It returned the result as ucs code, an kind of Unicode under
windows platform.
All I want to get is just a SEXP object containing the original utf-8
string, no matter what locale is set currently....

Suggestion: mkString(NULL) should be NA
I would like to propose that Rf_mkString(NULL) and Rf_mkChar(NULL)
return NA rather than segfault.
Case: the mkString() and mkChar() functions are convenient to wrap
strings returned by e.g. external C libraries into an R vector.
However sometimes a library returns NULL instead of a string when the
result is unavailable. In some C libraries this can happen
unexpectedly or is even undocumented.

translateChar in NewName in bind.c
...r-project.org
Date: Saturday, 10 June, 2017, 9:14 PM
In function 'NewName' in bind.c (https://svn.r-project.org/R/trunk/src/main/bind.c), in
else if (*CHAR(base)) ,
'translateChar' is used. Should it be
'translateCharUTF8' instead? The end result is marked as
UTF-8:
mkCharCE(cbuf, CE_UTF8)
Other cases already use
'translateCharUTF8'.

Using unicode from C interface of R
Hi ,
I am using C interface of R . If a unicode string is read , in what format
I could pass it back to R ?
I was trying to use the following
tpStr = ( char *)val;
SET_STRING_ELT(innerList , 0, mkChar(tpStr));
It does not work .
If I pass it back from as RAW format to R , what package is there to read
it ? I mean package for interpreting RAW data .
Thanks,
Sandip
