Hello at all,

I see the default font Segoe UI of windows is able to write all or nearly all the UNICODE characters

I can named easily a folder with : Miscellaneous symbols, Mongolian, Syriac, Chinese, etc .... and that ...without adding something or download other font

Then i say to me, if i use the same font Segoe UI than Windows in my lover IDE PB, i can also writing all the UNICODE characters inside him

And well no

in the IDE the SEGOE font not be able to write all the UNICODE characters, i obtain numerous interrogation point "?" in place, and i not understand why

Thanks in advance for your help

Have a good day

Salut KCC,

Not all of them, just those that are present in the charsets.
Some Unicode ranges are not supported.
E.g.: Code 127199 is present, range [127200-127369] is not but 127370 is.
It may also depend on the font version.

In IDE, Consolas font do the job too.

Also, the '?' is often the sign of a problem converting from utfX to utfY or ASCII.

Code: Select all

EnableExplicit
Define *mem, i, *c.Character, max = $FFFF, count, CountCharacter = 100
*mem = AllocateMemory(max * 2 + max * 2 / CountCharacter + 4)
*c = *mem
If *mem
	For i = 32 To max
		*c\c = i
		*c + 2
		count + 1
		If count > CountCharacter
			*c\c = 10
			*c + 2
			count = 0
		EndIf
	Next
	*c\c = 0
	SetClipboardText(PeekS(*mem))
	FreeMemory(*mem)
EndIf

"Salut" Boddhi

Aaah OK ! thanks for your precious explanation

I stupidly believed that if it's the same name of font, it's exactely the full font

And perhaps Windows download in background, or do something automaticaly for can write all the characters without user intervention ?
And PB IDE not do that

I use the usefull code of AZJIO for see that neither SEGOEI nor CONSOLAS can write all the characters, numerous ? are writing

Perhaps it's possible to create a simple simple GadgetEditor who can writing all the characters of the world like Windows do ? and adding it into tools of IDE, just for the moment where we coding application using UNICODE of the word

In all case again thanks

@AZJIO
Whaoooouuuhh !!!
Very splendid idea you have, and give to me, thanks a lot

Thanks to your nice code i can see, in one click all the table of characters the IDE can write

in fact....not so much

Fortunately, and for once, Windows is much less lazy, because with the poor quantity of characters the IDE can write, i can't use my idea of "Folder one letter name"

Again thanks for your usefull tool, i keep in preciously in my pocket

I have do a little test with nice tool of AZJIO and see the native EditorGadget() of PB can write numerous foreigners characters

Surely not all, but nothing to see with PB IDE

1/ I don't know the font it use ?
2/ Perhaps it's possible to boost it for it can write all characters of the world ?

Code: Select all

Define *mem, i, *c.Character, max = $FFFF, count, CountCharacter = 100
 
OpenWindow(0, 0, 0, 1900, 1000, "EditorGadget", #PB_Window_SystemMenu)
EditorGadget(0, 8, 8, 1876, 975)
 
*mem = AllocateMemory(max * 2 + max * 2 / CountCharacter + 4)
*c = *mem

If *mem

 For i = 32 To max
     
  *c\c = i
  *c + 2
  count + 1

  If count > CountCharacter
   *c\c = 10
   *c + 2
   count = 0
  EndIf

 Next

 *c\c = 0
 FreeMemory(*mem)
 SetGadgetText(0, PeekS(*mem))
  
 Repeat
  WindowEvent()
 Until WaitWindowEvent() = #PB_Event_CloseWindow
 
EndIf

1) The default system font: If no change, on Win10, "SEGOE UI" and on Win11, "SEGOE UI variable"
2) As already said, it depends on the used font and its supported Unicode ranges. I needed such a font with all ranges supported for a tool and never found. Even DejaVu font can't do better.

And I don't think I'm saying stupidity when I say that EditorGadget() can only display one font per gadget.

Did you try GNU Unifont?

Thanks for your new explanation

Darn good, AZJIO !
How did you come up with the fancy number you used to reserve memory ?

max * 2 - number of characters, 2 bytes for each character.
max * 2 / CountCharacter - number of lines. For each line you need to allocate space for the end of line character - LF.
add space for Null at the end.

Brilliant. And thanks for shining some light into my dim brain…
