U+A721 "꜡" Modifier Letter Stress and Low Tone Unicode Character

U+A721 "꜡" Modifier Letter Stress and Low Tone is a diacritic-like symbol used in certain phonetic transcription systems, most notably in the Uralic Phonetic Alphabet, to indicate a combination of stress and a low tone on the preceding vowel or syllable. Resembling a small, raised Latin letter "a" with a double acute or umlaut-like mark, it serves to modify the pronunciation of a base character by signaling both a specific level of prosodic emphasis and a lower pitch. This character is classified under the "Modifier Letters" block in Unicode, and its usage helps linguists and language experts accurately represent the tonal and stress patterns found in languages such as some Uralic or African languages, though it is not commonly encountered in everyday writing.
