Thai script "compresses" quite well compared to English because it does not use spaces between words, the vowel "a" is implicit, and many (but not all) other vowels are diacritics, not full letters. However, tone marking is inefficient (diacritics and silent letters), there are many duplicate letters for consonants, and the writing system and spoken language have diverged quite a bit.
