Regex Editor & Tester

Despite the character class spanning from NUL to 'A' and from '[' all the way to U+10FFFF (the 'entire world and more'), the negation means this regex actually matches only the 21 uppercase English consonants B, C, D, F–H, J–N, P–T, V–Z — every capital letter except the vowels A, E, I, O, U. The 'u' flag enables the huge Unicode range, and 'g' finds all occurrences. Useful for matching consonant initials, word games, or linguistic text analysis.
