"Bullet-proof" way to get ascii string in unicode only scenary

"Bullet-proof" (I think) to assign an ascii string to a string variable in the 'only unicode' PB compiler versions:
Code: Select all
Macro AsignarCadenaAscii(variable,cadena,terminacion=|0)
;Carga una cadena de caracteres ascii extendido en una variable
variable#=Space(Len(cadena#))
PokeS(@variable#,cadena#,Len(cadena#),#PB_Ascii#terminacion#)
EndMacro
AsignarCadenaAscii(var$,"Hello World!")
ShowMemoryViewer(@var$,Len("Hello World!")+1)
And another one, I think also "bullet-proof":
Code: Select all
var$="Hello World!"
CopyMemory(Ascii(var$),@var$,Len(var$)+1)
ShowMemoryViewer(@var$,2*Len(var$)+1)

You can't use string functions to a variable, so it doesn't make sense.

It is really a very bad solution to overwrite a unicode string with Ascii.
You simply can't use it anymore.
You can use this:
Code: Select all
*AsciiBuffer = Ascii("Hello world")
If *AsciiBuffer
ShowMemoryViewer(*AsciiBuffer, MemorySize(*AsciiBuffer))
FreeMemory(*AsciiBuffer)
EndIf
which makes more sense.

This is not a trick, more like a hack which isn't recommended

To calculate the len from an immediate unicode input string.
Len = len(input)
Len = len + (len&1)
Str.s = space(len)
Then you can poke it.
see my last post in your other thread.
