Indic Positional Category - Visual Order Left

Visual Order Left is a classification used for certain Indic script characters, such as vowel signs that appear to the left of their base consonant, unlike typical right–placed marks. This value indicates that the glyph is visually ordered to the left, but it does not alter the logical or phonetic order of the text; instead, it guides rendering engines to position the mark correctly when displaying the script. Characters with this value are often reordered during shaping, so that the visual output matches the expected orthographic form while the stored text retains its standard logical sequence. This ensures correct display for scripts like Bengali or Tamil, where such left–side vowel signs are common.
