While (again) wondering why non-Latin characters are being garbled when metadata from TIFFTAGS are being read, I looked for the cause of this in QgsGdalProvider::metadata().

This uses the function QgsRasterDataProvider::cStringList2Q_ to read a c-stringlist.

There is a missing QString::fromUtf8() when the string is being read:

strings.append( QString::fromUtf8(stringList[i]) );

Before:

TIFFTAG_IMAGEDESCRIPTION[1811 Grundriss von Berlin / von neuem aufgenommen und mit Genehmigung der Königl. Academie der Wissenschaften hrsg. von J. C. Selter. Gestochen von C. Mare] 

After:

TIFFTAG_IMAGEDESCRIPTION[1811 Grundriss von Berlin / von neuem aufgenommen und mit Genehmigung der Königl. Academie der Wissenschaften hrsg. von J. C. Selter. Gestochen von C. Mare]

This seems to be the only function inside QgsRasterDataProvider that needs such handling.

QgsOgrProvider uses a similar logic

• in the FROM8 and TO8 macros, where QString::fromUtf8() is also used

Since this is mostly metadata that is being read

• one can assume that non-latin characters will often be used
