Linux kernel source tree
Zero-width Unicode code points are causing misalignment in vertically aligned content, disrupting the visual layout. Let's handle zero-width code points more intelligently. Double-width code points are stored in the screen grid followed by a white space code point to create the expected screen layout. When a double-width code point is followed by a zero-width code point in the console incoming bytestream (e.g., an emoji with a presentation selector) then we may replace the white space padding by that zero-width code point instead of dropping it. This maximize screen content information while preserving proper layout. If a zero-width code point is preceded by a single-width code point then the above trick is not possible and such zero-width code point must be dropped. VS16 (Variation Selector 16, U+FE0F) is special as it typically doubles the width of the preceding single-width code point. We handle that case by giving VS16 a width of 1 instead of 0 when that happens.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
