Problems displaying UTF8 characters in tcc 32

[drrob1]

I have a small program written in Go, that needs to display matrices. On linux in bash, the special characters display as large matrix brackets. And on Win 11, stand-alone (detached) cmd.exe, these characters display as large matrix brackets.
But in tcc 32, they merely display as small square w/ a circle inside, which I think indicates an invalid character.

This sounds to me like a bug in tcc 32, 31 and 30. I did not test earlier than that.

The UTF8 code points are 0x23a1 .. 0x23a6. Their decimal values are 9121 .. 9126.

A simple matrix program that shows this is http://drrws.com/mattest2a.exe
The source is at https://github.com/drrob1/src/mattest2a.go

How do I get tcc to correctly show matrix brackets?

Is this in a Take Command tab window running TCC, or TCC running stand-alone? (If the latter, TCC has nothing to do with it - Windows is responsible for displaying characters in the console windows.)

Both
Why do these characters display correctly in stand-alone cmd.exe but not in tcc?

Most likely cause - you're not using the same font in both cmd and tcc.

Other possible causes - you have different console settings for cmd and tcc, and / or your console code page is different.

How do I determine which fonts I'm using in them, and how to I get the tcc font to be the same as cmd?

Thet show in TCMD but they are initially corrupted.

When TCMD is obscured and brought to the foreground (redrawn) they look better.

This is handled by Windows. Go to the console properties (click on the icon on the left of the cmd / tcc caption bar, then select Properties), and click on the Font tab.

Also, try starting TCC inside your CMD window and see if the characters are displayed properly there.

Starting tcc inside cmd does work. It would be nice to know which font to use for tcc for it to just work there, too

Vincent, echo %@char[0x23a1], etc do not work for me.
Which font are you using? Mine is set for consolas 14.

Consolas regular 13 and that was in v32. It doesn't work in v31 with the same font.

Then the difference is either your font, your code page, or your console settings (all outside of TCC's control).

Do a CHCP in your CMD and your TCC sessions and ensure they are the same.

Did you check your console properties to see if you're using the same font and other console settings?
