I am using the document class scrbook. In the bibliography, there is only one entry where the author is a Tibetan. The bib entry looks like
@book{si-tu_min_1990,
location = {Sansal},
title = {Miṅ daṅ rtags rjes su ston pa’i bstan bcos ’Chi med
mdzod kyi rgya cher ’grel ba ’Dod ’jo’i ba mo. In:
Collected Works of the Great Tai’i Si tu pa kun
mkhyen chos kyi byun (sic) gnas bstan pa’i nyin
byed},
volume = {vol. 4, pp. 243–738, Vol. 5, pp. 1–422},
author = {Si tu Chos kyi ’byuṅ gnas},
date = 1990,
}
In this case, I want the name to appear as it is in the author field, whereas what I get is Chos kyi ’byuṅ gas, Si tu. How do I get this done?

titleandvolumefields a bit by including bits of data that should ideally live elsewhere. The entry type might also not be quite right: Maybe it's an@inbookinstead? – moewe May 29 '20 at 13:15
