How can I embed non-ASCII strings in a GRC file?

[tsuyoshimishina]

I want my add-on to display Japanese menu items, but when I write Japanese characters into the GRC file, I occasionally encounter an "illegal string" error during the build process of Visual Studio. This issue seems to occur randomly. Is there a way to resolve this?

I found this discussion on this board (written in 2011!) mentioning the "-q utf8" argument of the GRC compiler. Does it still hold in ARCHICAD 24?

Hi,

I'd like suggest you to check the following GSJP web site which is about how to create VS environment for Japanese add-on.

LChen,

Thank you for your reply.
Your suggestion gave me a hint to solve my problem.
The solution I found is modifying the command line of custom build tool for the GRC file specified in the properties dialog as following:

".\Support\Tools\Win\ResConv.exe" -m r -D WINDOWS -T W -c 0 -q utf8 utf8 -i "RINT\$(ProjectName).grc" -D _DEBUG -o "$(OutDir)\RO\$(ProjectName).grc.rc2"

(Added "-c 0" and replaced "-q utf8 1252" with "-q utf8 utf8")
