(?:nfc | :nfd | :nfkc | :nfkd) -> bool

unicode_normalized?(form = :nfc) → true or false

static VALUE
rb_str_unicode_normalized_p(int argc, VALUE *argv, VALUE str)
{
    return unicode_normalize_common(argc, argv, str, id_normalized_p);
}

Returns true if self is in the given form of Unicode normalization, false otherwise. The form must be one of :nfc, :nfd, :nfkc, or :nfkd.

Examples:

Example

"a\u0300".unicode_normalized?       # => false
"a\u0300".unicode_normalized?(:nfd) # => true
"\u00E0".unicode_normalized?        # => true
"\u00E0".unicode_normalized?(:nfd)  # => false

Raises an exception if self is not in a Unicode encoding:

Example

s = "\xE0".force_encoding('ISO-8859-1')
s.unicode_normalized? # Raises Encoding::CompatibilityError.
