unicode: introduce UTF-8 character database The decomposition and casefolding of UTF-8 characters are described in a prefix tree in utf8data.h, which is a generate from the Unicode Character Database (UCD), published by the Unicode Consortium, and should not be edited by hand. The structures in utf8data.h are meant to be used for lookup operations by the unicode subsystem, when decoding a utf-8 string. mkutf8data.c is the source for a program that generates utf8data.h. It was written by Olaf Weber from SGI and originally proposed to be merged into Linux in 2014. The original proposal performed the compatibility decomposition, NFKD, but the current version was modified by me to do canonical decomposition, NFD, as suggested by the community. The changes from the original submission are: * Rebase to mainline. * Fix out-of-tree-build. * Update makefile to build 11.0.0 ucd files. * drop references to xfs. * Convert NFKD to NFD. * Merge back robustness fixes from original patch. Requested by Dave Chinner. The original submission is archived at: <https://linux-xfs.oss.sgi.narkive.com/Xx10wjVY/rfc-unicode-utf-8-support-for-xfs> The utf8data.h file can be regenerated using the instructions in fs/unicode/README.utf8data. - Notes on the update from 8.0.0 to 11.0: The structure of the ucd files and special cases have not experienced any changes between versions 8.0.0 and 11.0.0. 8.0.0 saw the addition of Cherokee LC characters, which is an interesting case for case-folding. The update is accompanied by new tests on the test_ucd module to catch specific cases. No changes to mkutf8data script were required for the updates.

unicode: reduce the size of utf8data[] Remove the Hangul decompositions from the utf8data trie, and do algorithmic decomposition to calculate them on the fly. To store the decomposition the caller of utf8lookup()/utf8nlookup() must provide a 12-byte buffer, which is used to synthesize a leaf with the decomposition. This significantly reduces the size of the utf8data[] array.

unicode: introduce UTF-8 character database The decomposition and casefolding of UTF-8 characters are described in a prefix tree in utf8data.h, which is a generate from the Unicode Character Database (UCD), published by the Unicode Consortium, and should not be edited by hand. The structures in utf8data.h are meant to be used for lookup operations by the unicode subsystem, when decoding a utf-8 string. mkutf8data.c is the source for a program that generates utf8data.h. It was written by Olaf Weber from SGI and originally proposed to be merged into Linux in 2014. The original proposal performed the compatibility decomposition, NFKD, but the current version was modified by me to do canonical decomposition, NFD, as suggested by the community. The changes from the original submission are: * Rebase to mainline. * Fix out-of-tree-build. * Update makefile to build 11.0.0 ucd files. * drop references to xfs. * Convert NFKD to NFD. * Merge back robustness fixes from original patch.

To store the decomposition the caller of utf8lookup()/utf8nlookup() must provide a 12-byte buffer, which is used to synthesize a leaf with the decomposition.

unicode: introduce UTF-8 character database The decomposition and casefolding of UTF-8 characters are described in a prefix tree in utf8data.h, which is a generate from the Unicode Character Database (UCD), published by the Unicode Consortium, and should not be edited by hand. The structures in utf8data.h are meant to be used for lookup operations by the unicode subsystem, when decoding a utf-8 string. mkutf8data.c is the source for a program that generates utf8data.h. It was written by Olaf Weber from SGI and originally proposed to be merged into Linux in 2014. The original proposal performed the compatibility decomposition, NFKD, but the current version was modified by me to do canonical decomposition, NFD, as suggested by the community. The changes from the original submission are: * Rebase to mainline. * Fix out-of-tree-build. * Update makefile to build 11.0.0 ucd files. * drop references to xfs. * Convert NFKD to NFD. * Merge back robustness fixes from original patch. Requested by Dave Chinner. The original submission is archived at: <https://linux-xfs.oss.sgi.narkive.com/Xx10wjVY/rfc-unicode-utf-8-support-for-xfs> The utf8data.h file can be regenerated using the instructions in fs/unicode/README.utf8data. - Notes on the update from 8.0.0 to 11.0: The structure of the ucd files and special cases have not experienced any changes between versions 8.0.0 and 11.0.0. 8.0.0 saw the addition of Cherokee LC characters, which is an interesting case for case-folding. The update is accompanied by new tests on the test_ucd module to catch specific cases. No changes to mkutf8data script were required for the updates.

The structures in utf8data.h are meant to be used for lookup operations by the unicode subsystem, when decoding a utf-8 string. mkutf8data.c is the source for a program that generates utf8data.h. It was written by Olaf Weber from SGI and originally proposed to be merged into Linux in 2014. The original proposal performed the compatibility decomposition, NFKD, but the current version was modified by me to do canonical decomposition, NFD, as suggested by the community. The changes from the original submission are: * Rebase to mainline. * Fix out-of-tree-build. * Update makefile to build 11.0.0 ucd files. * drop references to xfs. * Convert NFKD to NFD. * Merge back robustness fixes from original patch. Requested by Dave Chinner. The original submission is archived at: <https://linux-xfs.oss.sgi.narkive.com/Xx10wjVY/rfc-unicode-utf-8-support-for-xfs> The utf8data.h file can be regenerated using the instructions in fs/unicode/README.utf8data. - Notes on the update from 8.0.0 to 11.0: The structure of the ucd files and special cases have not experienced any changes between versions 8.0.0 and 11.0.0. 8.0.0 saw the addition of Cherokee LC characters, which is an interesting case for case-folding. The update is accompanied by new tests on the test_ucd module to catch specific cases. No changes to mkutf8data script were required for the updates.

unicode: reduce the size of utf8data[] Remove the Hangul decompositions from the utf8data trie, and do algorithmic decomposition to calculate them on the fly. To store the decomposition the caller of utf8lookup()/utf8nlookup() must provide a 12-byte buffer, which is used to synthesize a leaf with the decomposition. This significantly reduces the size of the utf8data[] array.

The original submission is archived at: <https://linux-xfs.oss.sgi.narkive.com/Xx10wjVY/rfc-unicode-utf-8-support-for-xfs> The utf8data.h file can be regenerated using the instructions in fs/unicode/README.utf8data. - Notes on the update from 8.0.0 to 11.0: The structure of the ucd files and special cases have not experienced any changes between versions 8.0.0 and 11.0.0. 8.0.0 saw the addition of Cherokee LC characters, which is an interesting case for case-folding. The update is accompanied by new tests on the test_ucd module to catch specific cases. No changes to mkutf8data script were required for the updates.

unicode: reduce the size of utf8data[] Remove the Hangul decompositions from the utf8data trie, and do algorithmic decomposition to calculate them on the fly. To store the decomposition the caller of utf8lookup()/utf8nlookup() must provide a 12-byte buffer, which is used to synthesize a leaf with the decomposition. This significantly reduces the size of the utf8data[] array.

unicode: introduce UTF-8 character database The decomposition and casefolding of UTF-8 characters are described in a prefix tree in utf8data.h, which is a generate from the Unicode Character Database (UCD), published by the Unicode Consortium, and should not be edited by hand. The structures in utf8data.h are meant to be used for lookup operations by the unicode subsystem, when decoding a utf-8 string. mkutf8data.c is the source for a program that generates utf8data.h. It was written by Olaf Weber from SGI and originally proposed to be merged into Linux in 2014. The original proposal performed the compatibility decomposition, NFKD, but the current version was modified by me to do canonical decomposition, NFD, as suggested by the community. The changes from the original submission are: * Rebase to mainline. * Fix out-of-tree-build. * Update makefile to build 11.0.0 ucd files. * drop references to xfs. * Convert NFKD to NFD. * Merge back robustness fixes from original patch.
