 Unlike other Brahmi scripts, Tocharian has a second set of characters called "Fremdzeichen" that double up several of the standard consonants, but with an inherent "Ä" vowel.The eleven Fremdzeichen are most often found as substitutes for the standard consonant+virama in conjuncts, but they can be found in any context other than with the explicit "Ä" vowel mark.Fremdzeichen as consonant+virama is not found in later Tocharian texts.
