TCC: Unknown command "ääää"
Please note the additional spaces ("_") on *inuput* for tcc.exe. In both examples I entered "ääää", w/o any spaces. "option //unicodeoutput={yes|no}" makes no difference whatsoever. Retrieving the last input line in tcc.exe with ARUP gives me:

Please comment on this (I consider this a bug).

But if you try to actually *run* anything in CMD with UTF-8 set (like batch
files), you'll see that it doesn't support it. (Google "chcp 65001" for
more info on CMD UTF-8 follies.)

TCC supports ASCII and UTF-16 I/O. (CMD only supports ASCII.) If you want
to request UTF-8 support as well (doable, but it'll be reeaallll slooooowwww
because TCC will have to convert every character to/from UTF-16 so that
Windows can understand it) you can request it in the Feedback forum. If you
can convince a few dozen other people to vote for it, there's a good chance
it will be implemented in a future version.
Thanks for the answer Rex,


1) Codepage "65001" is actually defined as being "UTF-8", not "UTF-16" (whatever Microsoft thinks about it).

2) The fact that the behavior in TCC is different from the behavior of CMD tells me that you "are in between" the API and the console window, so you can influence things for the better (this is not CMD...).

3) I don't think that UTF-8 support would make things slow at all (especially as you would already be able to tell you're in UTF-8 mode after a "chcp 65001"); there are various editors around (e.g. gvim, Notepad++) which have no problems to handle *big* UTF-8 files (and thus conversions between the formats).

I'd like to be in codepage 65001 mode all the time. E.g. I'd be able to cat/type UTF-8 files w/o seeing "garbage"; I'd like to use certain Perl programs (using Win32::Console colored output) to produce readable output, etc.

On the input side I'd like TCC not to produce "garbage" (i.e. "spaced" letters) when typing e.g. Russian or German letters (cmp. my first post), something which CMD (at least) does.

So far I use codepage 1252, which - again at least - lets me do the latter.

Code pages are completely meaningless in Take Command (or any other GUI
app), and only (very) marginally relevant anymore for console apps.

UTF-16 and Unicode fonts have rendered them obsolete.

Please try the following:

chcp 65001
The output is:

It's not that that it don't see the correct characters (like 'ä' or 'л' for that matter), it's the spaces that are produced on input (which CMD does not produce).

And, I contradict: "type"ing a UTF-8 file in 65001 renders different output as "type"ing it in 1252.
