Stumbled over a Unicode filename issue (again), looking into it there are at least two issues (independent of the codepages [1] used on Windows):
* using the command "dir" yields a different result (and also showing
backslashes in the Unicode
part of the filename) than using "Address ... with":
E:\WU\Lehrveranstaltungen\2020ws\01-BP1-AutoWin-0164\studentenarbeiten\g1\test\oha>*testDir.rex*
displaying current directory using "dir":
-*\342\227\220*-fileNameWithUnicodeChar-U+25D0.txt testDir.rex
testSysFileTree.rex
---
displaying current directory using: ADDRESS SYSTEM "dir":
-*\342\227\220*-fileNameWithUnicodeChar-U+25D0.txt testDir.rex
testSysFileTree.rex
---
displaying current directory using: ADDRESS SYSTEM "dir" *WITH output using
(arr)*:
Volume in drive E is root_e Volume Serial Number is 0509-DBAB Directory of

testSysFileTree.rex 3 File(s) 1 284 bytes 2 Dir(s) 71 670 398 976 bytes free
---
* using SysFileTree() and then using SysFileExists() to test the existence of
the Unicode file
returned by SysFileTree() will yield .false:
E:\WU\Lehrveranstaltungen\2020ws\01-BP1-AutoWin-0164\studentenarbeiten\g1\test\oha>*testSysFileTree.rex*
using command "dir":
-\342\227\220-fileNameWithUnicodeChar-U+25D0.txt testDir.rex
testSysFileTree.rex
---
--- now using SysFileTree() and SysFileExists():
sysFileTree with pattern: "*" | found: 3 file(s)
1:
[E:\WU\Lehrveranstaltungen\2020ws\01-BP1-AutoWin-0164\studentenarbeiten\g1\test\oha\-?-fileNameWithUnicodeChar-U+25D0.txt]
*does NOT****exist! ~c2x=[453A5C5755...]*
2:
[E:\WU\Lehrveranstaltungen\2020ws\01-BP1-AutoWin-0164\studentenarbeiten\g1\test\oha\testDir.rex]
exists!
3:
[E:\WU\Lehrveranstaltungen\2020ws\01-BP1-AutoWin-0164\studentenarbeiten\g1\test\oha\testSysFileTree.rex]
exists!

These kind of filenames containing some Unicode character(s) pop-up more and
more, depending on the
student's background (who come from many parts of the world).
So something ought to be done about it.
---rony
P.S.: Also more and more Windows programs create/save text files encoded in
Unicode for which linein
and lineout ought to work as well.
