Re: Word boundaries

> How can I check what script a character belongs to?
    $ perl -Mutf8 -MUnicode::UCD=charinfo -E'say charinfo(ord
"为")->{script}'
    Han

Sanity checks:

    $ perl -Mutf8 -E'say "为" =~ /\p{Han}/'
    1

    $ uniprops -a1 为 | ack Script
    Script=Han
    Script=Hani

Let the regex engine help you advance the character counter.
