``` PdfMemDocument doc; PdfPainter painter; painter.SetPage(doc.CreatePage(PdfRect(0, 0, 500, 800)));
painter.SetFont(doc.CreateFont("Helvetica"));
painter.DrawText(0, 780, "Text 1");
PdfWin1250Encoding();
painter.SetFont(doc.CreateFont("Helvetica", false, false, false,
PdfEncodingFactory::GlobalWin1250EncodingInstance()));
painter.DrawText(0, 760, "Text 2");
painter.FinishPage();
doc.Write("a.pdf");
return 0;
```
In output pdf is only this font "6 0
obj<</Type/Font/BaseFont/Helvetica/Encoding/WinAnsiEncoding/FirstChar
0/LastChar 255/Subtype/Type1/Widths 7 0 R>>".
If I change second font for example to bold then there is also second font
with 1250 encoding "8 0
obj<</Type/Font/BaseFont/Helvetica/Encoding<</BaseEncoding/WinAnsiEncoding/Differences[
131/.notdef 136/.notdef 140/Sacute 141/Tcaron 143/Zacute".
When is podofo creating new font it first checks whether is font already
not present in its font cache comparing parameters family, bold, italic,
symbol and encoding so theoretically different encodings should be
supported but PdfWin1250Encoding compares equal to PdfWinAnsiEncoding
because PdfWin1250Encoding has parent PdfWinAnsiEncoding and so inherits
its GetID. If GetID is used only for encoding comparisons (which seems so)
then it should implement own GetID. I would rather not change
PdfSimpleEncoding::m_name as it is used as BaseEncoding key and so it
should stay WinAnsiEncoding for derived encodings. Same also for
PdfIso88592Encoding.
Proposed patch attached.
