+# ".key" as appropriate for the localization. The code that uses this data can
+# deal with the absence of an access key for an item.
+#
+# For gbk, gbk.bis and gbk.bis.key are used to trigger string changes in
+# localizations.

+# In the en-US version of this file, access keys are given to the following:

+# * All Japanese encodings
+#
+# For the items whose property key does not end in ".key" and whose value
+# includes "(" U+0028 LEFT PARENTHESIS, the "(" character is significant for
+# processing by CharsetMenu.jsm. If your localization does not use ASCII
+# parentheses where en-US does in this file, please file a bug to make
+# CharsetMenu.jsm also recognize the delimiter your localization uses.

+# LOCALIZATION NOTE (intl.accept_languages):
+# This is a comma-separated list of valid BCP 47 language tags.
+#
+# Begin with the value of 'general.useragent.locale'. Next, include language
+# tags for other languages that you expect most users of your locale to be
+# able to speak, so that their browsing experience degrades gracefully if
+# content is not available in their primary language.
+#
+# It is recommended that you include "en-US, en" at the end of the list as a
+# last resort. However, if you know that users of your locale would prefer a
+# different variety of English, or if they are not likely to understand
+# English at all, you may opt to include a different English language tag, or
+# to exclude English altogether.
+#
+# For example, the Breton [br] locale might consider including French and
+# British English in their list, since those languages are commonly spoken in
+# the same area as Breton:
+# intl.accept_languages=br, fr-FR, fr, en-GB, en
+intl.accept_languages=br, fr-FR, fr, en-US, en
+
+# LOCALIZATION NOTE (font.language.group):
+# This preference controls the initial setting of the language drop-down menu
+# in the Content > Fonts & Colors > Advanced preference panel.
+#
+# Set it to the value of one of the menuitems in the "selectLangs" menulist in
+# http://dxr.mozilla.org/mozilla-central/source/browser/components/preferences/fonts.xul
+font.language.group=x-western
+
+# LOCALIZATION NOTE (intl.charset.detector):
+# This preference controls the initial setting for the character encoding
+# detector. Valid values are ja_parallel_state_machine for Japanese, ruprob
+# for Russian and ukprob for Ukrainian and the empty string to turn detection
+# off. The value must be empty for locales other than Japanese, Russian and
+# Ukrainian.
+intl.charset.detector=
+
+# LOCALIZATION NOTE (pluralRule): Pick the appropriate plural rule for your
+# language. This will determine how many plural forms of a word you will need
+# to provide and in what order.
