Indic Positional Category - Top And Left

Top And Left is a positional value that describes how a vowel sign or dependent mark attaches to a consonant’s upper left corner, rather than sitting directly above, below, or to the right. This orientation occurs in certain Indic scripts where the matra curves or extends from the top-left edge of the base character, often wrapping around the glyph’s shoulder. It indicates a specific visual placement for rendering and reordering, ensuring that the mark appears correctly in shaping and syllable stacks. The value helps distinguish signs that start at the left side but rise upward, such as some forms of the short “i” vowel, from those that are purely left, right, or top positioned.
