Original Pull Request: https://github.com/microsoft/terminal/pull/16775

State: closed
Merged: Yes

Summary of the Pull Request

URL detection was broken again in #15858. When the regex matched, we calculate the column(cell) by its offset, we use forward or backward iteration of the column to find the correct column that displays the glyphs of _chars[offset].

abf5d9423a/src/buffer/out/Row.cpp (L95-L104)

However, when calculating the currentOffset we forget that MSB of _charOffsets[col] could be 1, or col is pointing to another glyph in preceding column.
