+ The default value is `SHIFT-JIS`.
+
core.symlinks::
If false, symbolic links are checked out as small plain files that
contain the link text. linkgit:git-update-index[1] and
This setting defaults to "refs/notes/commits", and it can be overridden by

NAME
----
- gitattributes - defining attributes per path
+ gitattributes - Defining attributes per path
SYNOPSIS
--------
catch potential problems early, safety triggers.
+`working-tree-encoding`
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Git recognizes files encoded in ASCII or one of its supersets (e.g.
+UTF-8, ISO-8859-1, ...) as text files. Files encoded in certain other
+encodings (e.g. UTF-16) are interpreted as binary and consequently
+built-in Git text processing tools (e.g. 'git diff') as well as most Git
+web front ends do not visualize the contents of these files by default.
+
+In these cases you can tell Git the encoding of a file in the working
+directory with the `working-tree-encoding` attribute. If a file with this
+attribute is added to Git, then Git reencodes the content from the
+specified encoding to UTF-8. Finally, Git stores the UTF-8 encoded
+content in its internal data structure (called "the index"). On checkout
+the content is reencoded back to the specified encoding.
+
+Please note that using the `working-tree-encoding` attribute may have a
+number of pitfalls:
+
+- Alternative Git implementations (e.g. JGit or libgit2) and older Git
+ versions (as of March 2018) do not support the `working-tree-encoding`
+ attribute. If you decide to use the `working-tree-encoding` attribute
+ in your repository, then it is strongly recommended to ensure that all
+ clients working with the repository support it.
+
+ For example, Microsoft Visual Studio resources files (`*.rc`) or
+ PowerShell script files (`*.ps1`) are sometimes encoded in UTF-16.
+ If you declare `*.ps1` as files as UTF-16 and you add `foo.ps1` with
+ a `working-tree-encoding` enabled Git client, then `foo.ps1` will be
+ stored as UTF-8 internally. A client without `working-tree-encoding`
+ support will checkout `foo.ps1` as UTF-8 encoded file. This will
+ typically cause trouble for the users of this file.
+
+ If a Git client, that does not support the `working-tree-encoding`
+ attribute, adds a new file `bar.ps1`, then `bar.ps1` will be
+ stored "as-is" internally (in this example probably as UTF-16).
+ A client with `working-tree-encoding` support will interpret the
+ internal contents as UTF-8 and try to convert it to UTF-16 on checkout.
+ That operation will fail and cause an error.
+
+- Reencoding content to non-UTF encodings can cause errors as the
+ conversion might not be UTF-8 round trip safe. If you suspect your
+ encoding to not be round trip safe, then add it to
+ `core.checkRoundtripEncoding` to make Git check the round trip
+ encoding (see linkgit:git-config[1]). SHIFT-JIS (Japanese character
+ set) is known to have round trip issues with UTF-8 and is checked by
+ default.
+
+- Reencoding content requires resources that might slow down certain
+ Git operations (e.g 'git checkout' or 'git add').
+
+Use the `working-tree-encoding` attribute only if you cannot store a file
+in UTF-8 encoding and if you want Git to be able to process the content
+as text.
+
+As an example, use the following attributes if your '*.ps1' files are
+UTF-16 encoded with byte order mark (BOM) and you want Git to perform
+automatic line ending conversion based on your platform.
+
+------------------------
+*.ps1 text working-tree-encoding=UTF-16
+------------------------
+
+Use the following attributes if your '*.ps1' files are UTF-16 little
+endian encoded without BOM and you want Git to use Windows line endings
+in the working directory. Please note, it is highly recommended to
+explicitly define the line endings with `eol` if the `working-tree-encoding`
+attribute is used to avoid ambiguity.
+
+------------------------
+*.ps1 text working-tree-encoding=UTF-16LE eol=CRLF
+------------------------
+
+You can get a list of all available encodings on your platform with the
+following command:
+
+------------------------
+iconv --list
+------------------------
+
+If you do not know the encoding of a file, then you can use the `file`
+command to guess the encoding:
+
+------------------------
+file foo.ps1
+------------------------
+
+
`ident`

-EXAMPLE
--------
+EXAMPLES
+--------
If you have these three `gitattributes` file:
#
# When cross-compiling, define HOST_CPU as the canonical name of the CPU on
# which the built Git will run (for instance "x86_64").
+#
+# Define RUNTIME_PREFIX to configure Git to resolve its ancillary tooling and
+# support files relative to the location of the runtime binary, rather than
+# hard-coding them into the binary. Git installations built with RUNTIME_PREFIX
+# can be moved to arbitrary filesystem locations. RUNTIME_PREFIX also causes
+# Perl scripts to use a modified entry point header allowing them to resolve
+# support files at runtime.
+#
+# When using RUNTIME_PREFIX, define HAVE_BSD_KERN_PROC_SYSCTL if your platform
+# supports the KERN_PROC BSD sysctl function.
+#
+# When using RUNTIME_PREFIX, define PROCFS_EXECUTABLE_PATH if your platform
+# mounts a "procfs" filesystem capable of resolving the path of the current
+# executable. If defined, this must be the canonical path for the "procfs"
+# current executable path.
+#
+# When using RUNTIME_PREFIX, define HAVE_NS_GET_EXECUTABLE_PATH if your platform
+# supports calling _NSGetExecutablePath to retrieve the path of the running
+# executable.
+#
+# When using RUNTIME_PREFIX, define HAVE_WPGMPTR if your platform offers
+# the global variable _wpgmptr containing the absolute path of the current
+# executable (this is the case on Windows).
+#
+# Define DEVELOPER to enable more compiler warnings. Compiler version
+# and family are auto detected, but could be overridden by defining
+# COMPILER_FEATURES (see config.mak.dev)
+#
+# When DEVELOPER is set, DEVOPTS can be used to control compiler
+# options. This variable contains keywords separated by
+# whitespace. The following keywords are are recognized:
+#
+# no-error:
+#
+# suppresses the -Werror that implicitly comes with
+# DEVELOPER=1. Useful for getting the full set of errors
+# without immediately dying, or for logging them.
+#
+# extra-all:
+#
+# The DEVELOPER mode enables -Wextra with a few exceptions. By
+# setting this flag the exceptions are removed, and all of
+# -Wextra is used.

+ # Command classification list
+ # ---------------------------
+ # All supported commands, builtin or external, must be described in
+ # here. This info is used to list commands in various places. Each
+ # command is on one line followed by one or more attributes.
+ #
+ # The first attribute group is mandatory and indicates the command
+ # type. This group includes:
+ #
+ # mainporcelain
+ # ancillarymanipulators
+ # ancillaryinterrogators
+ # foreignscminterface
+ # plumbingmanipulators
+ # plumbinginterrogators
+ # synchingrepositories
+ # synchelpers
+ # purehelpers
+ #
+ # The type names are self explanatory. But if you want to see what
+ # command belongs to what group to get a better picture, have a look
+ # at "git" man page, "GIT COMMANDS" section.
+ #
+ # Commands of type mainporcelain can also optionally have one of these
+ # attributes:
+ #
+ # init
+ # worktree
+ # info
+ # history
+ # remote
+ #
+ # These commands are considered "common" and will show up in "git
+ # help" output in groups. Uncommon porcelain commands must not
+ # specify any of these attributes.
+ #
+ # "complete" attribute is used to mark that the command should be
+ # completable by git-completion.bash. Note that by default,
+ # mainporcelain commands are completable so you don't need this
+ # attribute.
+ #
+ # As part of the Git man page list, the man(5/7) guides are also
+ # specified here, which can only have "guide" attribute and nothing
+ # else.
