to transcode the paths to UTF-8. As an example, Perforce on Windows
often uses "cp1252" to encode path names.
+git-p4.fallbackEncoding::
+ Perforce changeset descriptions can be in a mixture of encodings.
+ Git-p4 first tries to interpret each description as UTF-8. If that
+ fails, this config allows another encoding to be tried. You
+ can specify, for example, "cp1252". If instead of an encoding,
+ you specify "replace", UTF-8 will be used, with invalid UTF-8
+ characters replaced by the Unicode replacement character. If you
+ specify "none" (the default), there is no fallback, and any non
+ UTF-8 character will cause git-p4 to immediately fail.
+
git-p4.largeFileSystem::
Specify the system that is used for large (binary) files. Please note
that large file systems do not support the 'git p4 submit' command.
