I would like to see the functions #.asc() and #.chr() added. I don't know if there are emoji characters available in Windows, but there should be some symbol characters that would be useful. To find them, we could built an SPL ASCII character display and selection program using these functions.

In SPL working with characters is much more sophisticated. It works with Unicode characters of different complexity.
You can check "rosetta\string length.txt" program example to see how SPL treats characters. Simple ASC() function is not enough.

Similarly, it is possible to convert bytes to Unicode string with #.str function:
Code: Select all
a = [4Ah, 00h, 32h, 03h, 6Fh, 00h, 32h, 03h, 73h, 00h, 32h, 03h, E9h, 00h, 32h, 03h]
#.output(#.str(a))
Result:

Of course it can be done by just

Thanks, Mr. K.
Windows has come a long way with characters! I will need to study this.

Here is a slight modification of the code that draws the text instead of outputting to the console
Another surprise - for me, anyway. The characters lose their colors.
Code: Select all
i = 1
> n, 0..ffh
a[i] = n
i += 1
a[i] = 26h
i += 1
<
#.fontsize(60)
> t, 1..300,30
#.drawtext(10,50+t*2.4,#.mid(#.str(a),t,20))

Because they are not text characters anymore but graphics symbols
Code: Select all
i = 1
> n, 0..ffh
a[i] = n
i += 1
a[i] = 26h
i += 1
<
#.fontsize(60)
> t, 1..300,30
#.drawcolor(#.hsv2rgb(t/300*360,1,1):3)
#.drawtext(10,50+t*2.4,#.mid(#.str(a),t,20))

I found a link to the Windows Unicode table:
https://unicode-table.com/en/
One of the characters it shows is a checkmark ✓. This would make a good indicator for multiple selections in a list.
It didn't appear in the output when I ran your code above. What upper limit should the loop be set for to output the entire Unicode table?

There is no upper limit. Unicode table is more than 65000 character codes. In the code above there are only 256 characters with codes from 2600 to 26FF.
