awthemes with Tcl 9 causes on some Windows computers this error:

I fixed the issue in _readFile by adding the line "fconfigure $fh

proc _readFile { fn } {
set fh [open $fn]
fconfigure $fh -profile tcl8
set fs [file size $fn]
set data [read $fh $fs]
close $fh
return $data
}

I found the repo on sourceforge but could not find an option to open a
ticket or make a pull request...

Hi,
I also use awdark theme on Windows and I did not saw such issue.
And no users of my app did report such issue.

Does you tcl/tk is compiled with -municode (if that matters....)?

The SVG images contained in awthemes 10.4.0 can all be read using _readFile with Tcl/Tk 9.0.2.
Did you change some of these files?

I would recommend to read the files in binary mode, i.e. set fh [open $fn "rb"] instead of using the -profile option, which does not work with Tcl/Tk 8.

The error occures until now on just one of many tested computers.
The difference is (to my knowlege) that this computer operates on
Windows Server 10, not Windows Home/Professional 11.
Other differences could of course exist.

Okay, I guess it's not problem to remove "-profile tcl8" and add "open
$fn rb" instead.
The questions is, how can we update the official package so that this
will not happen again?

The package is orphaned. A maintainer is required.
Great wizard Brad Lanam was idssapointed by the release politics and
quitted Tk. One way to get it maintained would be to add it to the
orphaned packages repository at github.
To my knowledge, Paul and Christian have updated versions in their copies.

Take care,
Harald

The awthemes 10.4.0 version in BAWT is identical to the original version from SourceForge.
