 		'enableDeprecationLog' => 'file',		// Commalist: Enables the logging of deprecated methods and functions. Default is 'file'. The following options are allowed: 'file': The log file will be written to typo3conf/deprecation_[hash-value].log  'devlog': The log will be written to the development log  'console': The log will be displayed in the Backend's Debug Console. The logging options can be combined by comma-separating them.
 		'maxFileNameLength' => 60,				// Integer: This is the maximum file name length. The value will be taken into account by basic file operations like renaming or creation of files and folders.
 		'UTF8filesystem' => FALSE,				// Boolean: If true and <a href="#BE-forceCharset">[BE][forceCharset]</a> is set to utf-8, then TYPO3 uses utf-8 to store file names. This allows for accented Latin letters as well as any other non-latin characters like Cyrillic and Chinese.
+		'UTF8characterLocale' => '',			// String: Default character locale (LC_CTYPE) setting for UTF-8 (e.g. "en_US@utf-8"). This is handy in combination with enabling UTF8filesystem support on servers that have a non-UTF-8 locale.
 		'lockingMode' => 'simple',					// String: Define which locking mode is used to control requests to pages being generated. Can be one of either "disable" (no locking), "simple" (checks for file existance), "flock" (using PHPs <a href="http://php.net/flock" target="_blank">flock()</a> function), "semaphore" (using PHPs <a href="http://php.net/sem-acquire" target="_blank">sem_acquire()</a> function). Default is "disable".

 		'reverseProxyHeaderMultiValue' => 'none',		// String: "none","first","last": defines which values of a proxy header (eg HTTP_X_FORWARDED_FOR) to use, if more than one is found. "none" discards the value, "first" and "last" use the first/last of the values in the list.
