Reply #35: The judge can indeed, and I fail to see what "foreigner" has to do with it

[Spider Jerusalem]

if the defence calls character witnesses to proclaim that they know DSK quite well and he is yes, a seducer and a womaniser, but not at all a man who would behave in this way to a woman, then the prosecution may call witnesses such as Mlle. Banon to rebut with evidence of the defendant's supposed bad character and propensity for behaviour in line with the offence he's charged with.


On edit: it can be allowed, whether it can be obtained is something else (a subpoena from a US court would not be seen as binding by a French citizen in France, for instance, although testimony may also be arranged by sworn deposition).
