Is it possible to convert between Unicode normal forms in PHP?

Question

For example, in one Unicode normal form á is always represented as an unaccented letter a and a combining accent mark, in another it must be a single pre-combined Unicode character. How would I convert between these forms in PHP?

Answer 1

Unicode normalization is provided by the intl extension and its Normalizer class.
