Cannot load XISF where FITs header contains Greek characters

[AnakChan]

GraXpert error when trying to load an XISF file where there are Greek characters in the FITs Header.

Sample XISF: https://www.dropbox.com/s/2etenseo9zchs2y/masterLight_BIN-1_9576x6388_EXPOSURE-60.00s_FILTER-Luminance_mono_autocrop.xisf?dl=0 FITS Header entry, TELESCOP: Takahashi µ250CRS

Temp workaround: Save XISF to FITS which removes the Greek character from the FITS Header
