You previously posted on the following thread. Did the solution provided there solve the issue?

> [@Build Slicer failed on win10](https://discourse.slicer.org/t/build-slicer-failed-on-win10/15674/6):

> Probably the issue is that your system code page is set to 950 (Traditional Chinese) and c:\S4R\LibArchive\libarchive\archive\_read\_support\_format\_rar5.c contains characters that cannot be interpreted in this code page. The simplest is to remove the offending characters (remove entire line 74, it is just a comment): \* "Rar!→•☺·\x00" If you will keep running into similar errors then you may consider switching to Latin1 code page for the build.

I do see in one of the logs you posted that it warns the following:

> warning C4819: The file contains a character that cannot be represented in the current code page (950)
