Double Breve below/above

[Dirk Schmücker]

Hello, I am using Affinity Publisher on Windows. I am using Unicode glyphs U+035c (Combining Double Breve Below) and U+036c (Combining Double Inverted Breve) to produce ties below and above two characters. On the Publisher canvas, it looks good (screenshot 1), while exporting to a PDF makes the ties and characters overlap (screenshot 2). Any ideas how I could fix this? Thanks for your assistance, Dirk

Hello @Dirk Schmücker

I think you use the wrong glyph. And if I testing with various fonts, it is the font itself.

Have had testet with Calibri. The export is faulty. Exported with Dejavu, the result shows as expected.

Thank you, Komatös, changing the font only helps with the ties above, but not those below (the glyph U+035c is not even in the Dejavu font). Any other ideas? Cheers,

Dirk

P.S. Using Times New Roman, U+0361 produces the same faulty export as U+036c

P.P.S. Used a word processor to check the glyphs and the font, and it works ok. Must be something with APub ...

Could you please attach your test document?

And confirm you are using Times New Roman?

I have seen these double breves handled successfully in OpenType code, but I am not sure how or if it can work manually. It looks like in the PDF output the anchor points are ignored or broken, or it is a bug in the PDFlib, or ... ?

UPDATE: this does appear to be a bug.
Tested in TNR and multiple other fonts.
Tested your text and other text which includes those characters.
All did not work in APub.
All did work LibreOffice (Harfbuzz).

FYI: 036C is Combining Latin Small Letter R

Thank you, @LibreTraining, 

a) yes, I use Times New Roman, as included in Windows

b) U+036c was wrong, U+0361 was the glyph I used for the tie above. Sorry for the confusion.

c) Testdok and pdf are attached.

d) UPDATE: Exporting from AfPub to EPS or PNG works ok, but not to PDF.

Thanks for your time and energy, best regards,

Dirk

I printed my test doc to the ImagePrinter printer driver - some of it worked, some of it did not.
But I had other text combinations than just those that you had.

Printed your test doc to my ImagePrinter - it looks the same as the Export to PNG.

Some bugs here for sure.
