U+0E23 Thai Character Ro Rua

El Wikipedia tiene la siguiente información acerca de este punto de código:

The Thai script (Thai: อักษรไทย, RTGS: akson thai, pronounced [ʔàksɔ̌ːn tʰāj]) is the abugida used to write Thai, Southern Thai and many other languages spoken in Thailand. The Thai script itself (as used to write Thai) has 44 consonant symbols (Thai: พยัญชนะ, phayanchana), 16 vowel symbols (Thai: สระ, sara) that combine into at least 32 vowel forms, four tone diacritics (Thai: วรรณยุกต์ or วรรณยุต, wannayuk or wannayut), and other diacritics.

Although commonly referred to as the Thai alphabet, the script is in fact not a true alphabet but an abugida, a writing system in which the full characters represent consonants with diacritical marks for vowels; the absence of a vowel diacritic gives an implied 'a' or 'o'. Consonants are written horizontally from left to right, and vowels following a consonant in speech are written above, below, to the left or to the right of it, or a combination of those.
