Update of bug #56788 (project octave):
Status: None => Confirmed
Summary: The cd command does not work properly, you need to
write the name of the Russian directory in quotation marks, even if i => parse
error on command syntax with argument that starts with a non-ASCII character
_______________________________________________________
Follow-up Comment #1:
I can confirm this error on Debian. I suspect this is because Octave's parser
is not Unicode-aware.
The syntax that lets you run a function without parentheses is called "command
syntax". It requires that the parser recognizes that a function name is
followed by whitespace and then by printable characters which are not
operators.
If the first character is an ASCII character, then it works. For example
$ mkdir Dокументы
$ octave
>> cd Dокументы
>> pwd
ans = /home/mike/Dокументы
The same error occurs with any leading accented characters in Western
languages, for example
$ mkdir ábc
$ octave
>> cd ábc
parse error:
syntax error
>>> cd ábc
