Re: [TCLCORE] TIP 716 ready for comments

[Harald O. <har...@el...>]

Ashok,
you were totally correct.

Here is the relevant code snippet:

pStr = Tcl_GetStringFromObj(objv[PositionSPar],&lStr);
Tcl_UtfToExternalDString( NULL, pStr, lStr, &sPar1);
TextOut(pdlg.hDC, X0, Y0, Tcl_DStringValue( &sPar1 ), Tcl_DStringLength( 
&sPar1 ))

So, TextOutA gets utf-8 in TCL9 and tip-715 and cp12xx on TCL 8.6.

I wonder, that the manifest aparently has no influence on TextOutA.
Normally, it should work with 9.0, as data and interpretation is utf-8.

I don't want to dig too deep here.
TIP 715 is great and already the "encoding user" is very important.

Thanks for all,
Harald
