Fallback font applied too far in PDF output

[s_g]

Hi,

I'm encountering a problem with using fallback fonts for Unicode glyps not contained in the main font. In the PDF output produced, not only is the direct glyph “⦗” (U+2997) rendered in the fallback font (marked BLUE in the screenshot below), but also the following characters (marked RED in the screenshot below) use the fallback font, until a whitespace character is encountered.

I'm applying the default font rules, is this a known problem or am I overlooking something here? I tried giving different font-family rules and fallback font options, but the problem persists.

I would be happy about any suggestions or possible solutions.

Hello,

What PDF scenario are you using? DITA Map PDF - based on HTML5 & CSS or DITA Map PDF - based on XSL-FO?

We are using the HTML+CSS based workflow, where we generate an intermediate HTML5 file via XSLT and then have custom CSS rules for the PDF generation process.

Hello,

We are aware of this issue and I already added your vote to it.
As a workaround you can add a Zero Width Space (​) character after the ⦗ character.

I tested your workaround and it works, thank you for your quick and helpful response!

Hello,

Oxygen 28.1 is available in our website, in this version we have corrected how Chemistry handles fonts so you should not experience fonts change inside or after a word in PDF outputs anymore.
