是否有任何方法枚举Ruby中所有字符的Unicode属性?我可以使用Ruby 1.9的Regexp类来测试给定字符是否具有特定属性(例如，some_char =~ /p{P}/测试some_char是否为标点符号，等等)…但由于字符可以有多个属性(例如，(是标点符号和 ASCII等)，因此能够获得所有字符属性的列表将是很好的。
我可能可以用unicode_data.txt手工完成这个，或者不管它叫什么，但这似乎是一种可能已经在某处完成的事情。UnicodeUtils似乎没有这些线索，谷歌也没有发现任何明显的东西。谢谢!
你可以调用我的uniprops脚本。

你可能也想要独角兽，这样你就可以走另一条路了。下面是调用它的例子:
$ unichars -gns 'p{Cased}' 'p{Number}'
$ unichars 'R'
$ unichars 'S' '[vh]'
$ unichars 'S' 'p{space}'
$ unichars 'pL' 'p{Greek}'
$ unichars 'pL' 'p{Greek}' | um
$ unichars 'p{Age=6.0}' | um
$ unichars 'p{Lowercase}' 'P{Lowercase_Letter}'
$ unichars 'p{Lower}' 'P{Ll}' # same but easier to type
$ unichars -a 'p{alphabetic}' 'P{Letter}' | wc -l # 1006 code points
$ unichars -gas 'PL' 'p{Cased}'
$ unichars -gas 'P{MARK}' 'p{diacritic}' # 209 code points
$ unichars -gas 'pM' 'P{BC=NSM}'
$ unichars -gas 'p{Cased}' '[^p{CWL}p{CWT}p{CWU}]'
$ unichars -gas 'p{Dash}'
$ unichars -gas 'p{mark}' 'P{DIACRITIC}' # 1068 code points
$ unichars -gas 'grep { length > 1 } lc, ucfirst, uc'
$ unichars -gas 'uc ne ucfirst'
$ unichars -gasn NUM
下面是输出的一个例子:
$ unichars -gsn NUM 'int NUM ne NUM'
