@execstr unicode support

[TimButterfield]

I am learning Russian and have a folder with the first name of my tutor. @execstr changes the Cyrillic characters to ???.

C:\Users\tim\Documents\Language\яна>
echo %@truename[new_vocab.txt]
C:\Users\tim\Documents\Language\яна\new_vocab.txt

C:\Users\tim\Documents\Language\яна>
echo %@execstr[cd]
C:\Users\tim\Documents\Language\???

Try option //unicodeoutput=yes.

That worked. Thanks. It just seemed strange that, without the option change, it output unicode for one function, but not the other.

Hmmm! The difference may be that @EXECSTR[] writes to a (temporary) file, and "OPTION UnicodeOutput" deals with redirected (e.g., to a file) output.

If that's what's happening, and we are to be oblivious to the use of temp files, it would make more sense if @EXECSTR[] always used Unicode temporary files.

I don't know how robust this is, but it works in this simple experiment.

v:\> function execstru `%@exec[@option //UnicodeOutput=Yes]%@execstr[%$]%@exec[@option //UnicodeOutput=No]`

v:\> set zz=%@char[1071]%@char[1053]%@char[1072]

v:\> echo %zz
ЯНа

v:\> echo %@execstr[echo %zz]
???

v:\> echo %@execstru[echo %zz]
ЯНа

There may or may not be a temp file — I don't know. But UnicodeOutput also affects pipes.

Seen on Raymond Chen's blog today:

The saga begins in 1981. At this time, code pages roamed the earth....

Yeah. I was playing with pipes. The only internal (VIEW, too) I can correctly pipe unicode output to is LIST. For example,

v:\> echo %zz
ЯНа

v:\> option //unicodeoutput=Yes & echo %zz | tail & option //unicodeoutput=No
ЯНа

਀

I thought maybe this would change things, but it didn't.

v:\> alias utail `(option //unicodeoutput=Yes & tail & option //unicodeoutput=No)`

v:\> option //unicodeoutput=Yes & echo %zz | utail & option //unicodeoutput=No
ЯНа
