ProgramParameter() and utf8

[Kukulkan]

Hello,

I'm just wondering if older versions of PureBasic converted utf8 encoded commandline parameters to Unicode automatically? With PB5.21 I get the utf8 encoded string as unicode. This is ok so far and I can solve by using PeekS() and PokesS() but I think that older PB versions converted the utf8 parameter to unicode by themselves?

Any hints about this and how to deal with such commandline parameters?

IIRC, these commands never converted from utf8 to unicode automatically.

Ok, thanks Fred.

So I think UTF8 and manual conversion is the only way to securely submit commandline parameters to a PureBasic application if they contain unicode characters, right?

You mean on Linux or Windows ?

[Kukulkan]

Both. My application gets compiled on Windows, Linux and MacOS. I like to have it the same behaviour on all platforms. I think utf8 is the best. Do you agree?

As I'm compiling in Unicode, I have to convert the utf8 parameters to Unicode in my code:

Code: Select all

Procedure.s ConvertUTF8toUnicode(utf8String.s)
  ; works only if compiled in unicode mode!
  Protected result.s = ""
  Protected *a = AllocateMemory(Len(utf8String.s)+1)
  ; poke it as ascii
  PokeS(*a, utf8String.s,-1,#PB_Ascii)
  ; peek it as utf8
  result.s = PeekS(*a, -1, #PB_UTF8)
  FreeMemory(*a)
  ProcedureReturn result.s
EndProcedure

Best
