P4Client error due to diacritics

[fiha]

We have diacritics (é and è) in some of our filenames in our perforce depot. 

During Fisheye indexing an error is reported:

"Fri Sep 25 20:50:34 GMT+200 2020: Repository paused due to error com.cenqua.fisheye.rep.DbException: com.cenqua.fisheye.perforce.client.P4ClientException: Unable to get file log for //depot/Projects/H2/Sound/sfx/Weapons/shots/V�loce - Fire RR01.wav#1"

A question mark in diamond shape is displayed instead of é.

In SCM details the default charset is set as UTF8.

I am not sure why the p4 client is unable to handle Véloce.

How can we fix this?

I think I fixed it by modifying the charset into Windows-1252 but now I am running into a different problem so can't tell for sure.
