falcon.h and uprint doesn't do extended ASCII characters?

[SMcNeill]

Am I doing something wrong here, or is this just the way uprint is currently set up to work:

Code: QB64: [Select]

1. DECLARE LIBRARY "falcon"
2.     SUB uprint_extra (BYVAL x&, BYVAL y&, BYVAL chars%&, BYVAL length%&, BYVAL kern&, BYVAL do_render&, txt_width&, BYVAL charpos%&, charcount&, BYVAL colour~&, BYVAL max_width&)
3.     FUNCTION uprint (BYVAL x&, BYVAL y&, chars$, BYVAL txt_len&, BYVAL colour~&, BYVAL max_width&)
4.     FUNCTION uprintwidth (chars$, BYVAL txt_len&, BYVAL max_width&)
5.     FUNCTION uheight& ()
6.     FUNCTION uspacing& ()
7.     FUNCTION uascension& ()
8. END DECLARE
9.  
10.  
11. SCREEN _NEWIMAGE(800, 600, 32)
12. _FONT _LOADFONT("courbd.ttf", 20, "monospace")
13.  
14. _CONTROLCHR OFF
15. FOR i = 1 TO 255
16.     CLS
17.     r = uprint(0, 0, CHR$(i), 1, -1, 0)
18.     LOCATE 1, 20: PRINT CHR$(i), i
19.     SLEEP
20. NEXT

None of the ASCII characters below 32, or above 128 print with uprint.  I see Rho has a way to print unicode characters with uprint in his library collection -- do I need to write a routine to convert extended ascii characters to their unicode counterparts, and then print them character by character to have them render properly, or is there some simple trick which I'm missing here?

[luke]

The library very intentionally treats data as UTF-8 strings. You will need to convert non-ascii characters to their equivalent utf8 representation.

I think Rho might have the needed data tables in his falcon wrapper

[SMcNeill]

Even with Rho's conversion to UTF-8 characters, I'm still not getting many of the characters to render properly.  Anyone know what's wrong here.  Tell me I'm doing something simple, wrong.  ;)

And my apologies to @RhoSigma, as I've hacked the heck out of his code to test and paste the relevant portions of it into my own zombified test here.  I was trying to grab and examine only what I needed to get utf-8 characters to print, but  it seems even with all this, I'm still not getting many to display properly.

Does this require an unicode font, like cyberbit.ttf?  Does it work at all?  Or am I just doing something wrong here?

[RhoSigma]

Not sure what you're looking for, but running the code from your latest post it works all as expected to me. Ok, you just get the square for ASCII 0-31 and 127, but that's a matter of falcon.h, where those control chars are substituted with the square replacement character. If you want those, then you have to go into falcon.h and tweak it there.

[SMcNeill]

Some of the other characters are coming back blank for me; in the upper 180+ ranges.  It’s late tonight, but I can get you a list of all the non-characters tomorrow, if you want.  CHR$(240) is one I was trying to use earlier, but it doesn’t render at all, no matter what I try with it, so far.

[RhoSigma]

No problem here. All that chars showing up. Probably really differences in  the TTF font files from system to system, as you suggested the other day.

This is now giving me the whole character page with characters from CHR$(0) to CHR$(255).  I had an UTF8toUnicode function which I'd written before, but it generated an aray of up to 4bytes for my needs, and rather than work on converting it, I simply stole your's Rho -- if that's okay with you?  ;)

If it helps to get your things done, then just go ahead. That's why we're here, to share ideas and code of course.
