unicode_and_posix_properties

🌐 Master Unicode & POSIX Property Escapes​

Use \p{...} and POSIX classes like [:Alpha:] to build robust patterns for international text. Combine script and block properties for granular control.

# Match any Greek letter
greek = /\p{Greek}+/u
p "αβγ".match?(greek)  # => true

# Match any letter or number from any script
alnum = /[\p{L}\p{N}]+/u
p "英文123".scan(alnum)  # => ["英文123"]

POSIX shorthand:

# Match ASCII word chars only
ascii_word = /[[:word:]]+/  # equals [A-Za-z0-9_]
