|  | To update to the newer version of the Unicode standard, the latest | 
|  | released version of the UCD can be found here: | 
|  |  | 
|  | http://www.unicode.org/Public/UCD/latest/ | 
|  |  | 
|  | Then, build under fs/unicode/ with REGENERATE_UTF8DATA=1: | 
|  |  | 
|  | make REGENERATE_UTF8DATA=1 fs/unicode/ | 
|  |  | 
|  | After sanity checking the newly generated utf8data.c file (the | 
|  | version generated from the 12.1.0 UCD should be 4,109 lines long, and | 
|  | have a total size of 324k) and/or comparing it with the older version | 
|  | of utf8data.c_shipped, rename it to utf8data.c_shipped. | 
|  |  | 
|  | If you are a kernel developer updating to a newer version of the | 
|  | Unicode Character Database, please update this README.utf8data file | 
|  | with the version of the UCD that was used, the md5sum and sha1sums of | 
|  | the *.txt files, before checking in the new versions of the utf8data.c | 
|  | and README.utf8data files. |
