CONFIGURATION OPTIONS ===================== +Multibyte Character Support +--------------------------- + +Support for multibyte character sets that extend ASCII, such as UTF-8, is +under development but the code in the line editor is sufficiently stable to +be turned on by default in environments that provide full ISO 10646 support +including the preprocessor definition __STDC_ISO_10646__. + +The support can be explicitly enabled or disable with --enable-multibyte or +--disable-multibyte. Reports of systems where multibyte support was not +enabled by default but --enable-multibyte resulted in a usable shell would +be appreciated. The developers are not aware of any need to use +--disable-multibyte and this should be reported as a bug. + +The main shell is not yet aware of multibyte characters, so for example the +length of a scalar parameter will return the number of bytes, not +characters, and pattern tests likewise treat single bytes as if they were +characters. This means that pattern tests such as ? and [[:alpha:]] do not +work correctly with characters in multibyte character sets beyond the ASCII +subset. + Memory Routines --------------- @@ -2,8 +2,35 @@ CHANGES FROM PREVIOUS VERSIONS OF ZSH ------------------------------------- -Changes since zsh version 4.2.0 -------------------------------- +Major changes between versions 4.2 and 4.3 +------------------------------------------ + +- There is support for multibyte character sets in the line editor, + though not the main shell. See Multibyte Character Support in INSTALL. + +- New option PROMPT_SP, on by default, to work around the problem that the + line editor can overwrite output with no newline at the end. + +- New option HIST_SAVE_BY_COPY (on by default): history is saved by + copying and renaming instead of directly overwriting. + +- New redirection syntax e.g. {myfd}>file opens a new file descriptor + and stores the number in $myfd, so that >&$myfd will work.
