Configuration file not well encoded

The configuration file (in mods.d) of several modules are not encoded in UTF8 (altought theEncoding field is set to UTF-8).

I noticed some module descriptions contain invalid characters displayed as �.

To find all the invalid modules, I run the command file --mime-encoding * | grep -v utf-8 | grep -v us-ascii in the folder ~/.sword/InstallMgr/ftp.crosswire.org/mods.d.

Here is what I get :

ab.conf: iso-8859-1
chamorro.conf: iso-8859-1
finbiblia.conf: iso-8859-1
finpr.conf: iso-8859-1
gerelb1871.conf: iso-8859-1
gerlutherpredigten.conf: iso-8859-1
gersch.conf: unknown-8bit
globals.conf: binary
imitation.conf: iso-8859-1
jubilee2000.conf: iso-8859-1
rieger.conf: iso-8859-1
sml_BL_2008.conf: iso-8859-1
spavnt.conf: iso-8859-1
swe1917.conf: iso-8859-1
ukjv.conf: unknown-8bit
viet.conf: iso-8859-1
wulfila.conf: iso-8859-1

Note that others modules are concerned in other repositories.

I thought it doesn't worth to open bugs for all of these modules.
