New on CTAN: folarrow
folarrow provides arrows with three slanted strokes on the shaft, which denote the projection of a foliated bundle, for amscd, xy-pic and tikz-cd diagrams and for inline math. The inline arrows are single glyphs (Type 1 fonts for the common Type 1 math fonts, OpenType fonts for 49 OpenType math fonts) that copy from the PDF as arrows. The documentation is in English and Japanese.
The package’s Catalogue entry can be viewed at https://ctan.org/pkg/folarrow The package’s files themselves can be inspected at https://mirrors.ctan.org/fonts/folarrow/

Folarrow – Arrows with three strokes for the projection of a foliated bundle
This package provides arrows with three slanted strokes on the shaft, which denote the projection of a foliated bundle in foliation theory, for amscd, xy-pic and tikz-cd diagrams and for inline math. The strokes follow the arrowhead and the shaft of the current math font in every math style, and bold math.
The inline arrows are typeset with single glyphs including the strokes: Type 1 fonts made from the symbol fonts of Computer Modern, Latin Modern, newtx, txfonts, newpx and pxfonts (and their bold versions), and OpenType fonts made from 49 OpenType math fonts for unicode-math. They copy from the PDF as arrows (U+2190-U+2193). For other math fonts the strokes are drawn. The option lite draws all arrows and uses no other files.
The package works with pdfLaTeX, LuaLaTeX, XeLaTeX and upLaTeX+dvipdfmx. The documentation is in English and Japanese.
