> Accented Letters composed of Unicode base letter and combining accent are rendered wrong. E.g. with 0041 030B LATIN CAPITAL LETTER A WITH COMBINING DOUBLE ACUTE ACCENT the accent appears at the right hand side of the letter A, not above the letter A.
> The position is wrong for most of the sequences defined in the following spec:
> DIN SPEC 91379: Characters in Unicode for the electronic processing of names and data
> exchange in Europe; with digital attachment
> [https://www.xoev.de/downloads-2316#StringLatin]
> [https://www.din.de/de/wdc-beuth:din21:301228458]
>
> The correct rendering should look like the output of hb-view 2.6.8, see files DIN_SPEC_91379_Sequences*.pdf.
> The output of PDFBox is appended in pdfbox.pdf, which is created by running TestPdfbox.java. The sequences are read from file DIN_SPEC_91379_Sequences.txt.

> Font used for testing: NotoSansMono-Regular.ttf, see [https://www.google.com/get/noto/]
