+config UNICODE_BIDI_SUPPORT
+ bool "Bidirectional character-aware line input"
+ default n
+ depends on UNICODE_SUPPORT && !UNICODE_USING_LOCALE
+ help
+ With this option on, right-to-left Unicode characters
+ are treated differently on input (e.g. cursor movement).
+
+config UNICODE_NEUTRAL_TABLE
+ bool "In bidi input, support non-ASCII neutral chars too"
+ default n
+ depends on UNICODE_BIDI_SUPPORT
+ help
+ In most cases it's enough to treat only ASCII non-letters
+ (i.e. punctuation, numbers and space) as characters
+ with neutral directionality.
+ With this option on, more extensive (and bigger) table
+ of neutral chars will be used.
+
+config UNICODE_PRESERVE_BROKEN
+ bool "Make it possible to enter sequences of chars which are not Unicode"
+ default n
+ depends on UNICODE_SUPPORT
+ help
+ With this option on, on line-editing input (such as used by shells)
+ invalid UTF-8 bytes are not substituted with the selected
+ substitution character.
+ For example, this means that entering 'l', 's', ' ', 0xff, [Enter]
+ at shell prompt will list file named 0xff (single char name
+ with char value 255), not file named '?'.
