Frenchfrie commented on PDFBOX-5219:
------------------------------------
I attached both the GDrive [^expected result (from GDocs).pdf] and the PDFBox
[^pdfbox_generated_with_invisible_emojis_afterLOD.pdf] generated document.
However, I had to open and export the latter through LibreOffice Draw because
Jira failed to accept it (with an internal error). There must be PDF error but
the content shown is identical.

> Some fonts legitimately do not have a 'loca' table as specified in [Apple
> documentation|https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6loca.html]:
> ??The {{'loca'}} table only used with fonts that have TrueType outlines (that
> is, a [{{'glyf'}}
> table|https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6glyf.html]).
> Fonts that have no TrueType outlines do not require a {{'loca'}} table.??
> This has led to some misunderstanding in the NotoColorEmoji google font
> project as testified by those issues :
> [https://github.com/googlefonts/noto-emoji/issues/190]
> [https://github.com/googlefonts/noto-emoji/issues/288]
> Also reproduced with JoyPixels.ttf from [https://www.joypixels.com/]
> installed through [package
> manager|https://archlinux.org/packages/community/any/ttf-joypixels/].
>
> The TTFParser class just do not accept this font based on the absence of the
> 'loca' table and it can be verified with the simple test:
> {code:java}
> PDType0Font.load(doc, getClass().getResourceAsStream("NotoColorEmoji.ttf"),
> false);
> {code}
