Every timeline in MeshTerm is made of braille characters, and almost no monospace font has them. Reading the cmap of every font on this machine: Consolas, Lucida Console, Hack Nerd Font, JetBrains Mono, Fira Code and Source Code Pro all carry zero of the 256 -- and so does DejaVu Sans *Mono*, which is where the widespread "install DejaVu for braille" advice falls down. DejaVu *Sans*, proportional, has all 256. That is the whole trick: terminals fall back to a proportional face for the block, and the charts have always been drawn by a font nobody chose. Which is fine everywhere except the one host that does no fallback. In the classic Windows console -- what a double-clicked build gets -- Consolas draws 57 of the 122 characters we use and none of the charts. So MeshTerm now bundles Cascadia Mono PL (SIL OFL, licence beside it) and offers it there. Cascadia is one of two mainstream coder fonts with the block; the PL build adds the powerline separators the path lines want, and at 723KB covers exactly what the 2.4MB Nerd Font build does. A machine that already has Cascadia -- every Windows 11, anyone with Windows Terminal -- is only offered the switch. Both halves are verified on Windows 10 22H2, and neither needs admin: a font installs for one user under %LOCALAPPDATA% with AddFontResourceW and an HKCU registration, and SetCurrentConsoleFontEx selects a face the console's own properties dialog will not even list -- that dialog offers only what is under the machine-wide Console\TrueTypeFont key, which here is Lucida Console and Consolas, so without that API the font could be installed and still unpickable. Declining is answered with what declining looks like -- charts as rows of boxes -- and asked once more, because a reader who has never seen the app cannot picture what it costs. A second no is remembered in the console_font preference and never raised again. Windows locks a font file once loaded: it cannot be deleted even elevated, even after restarting the font cache, until the next logon. So nothing here offers to uninstall one, and the install is written to be repeatable instead of reversible. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

PREAMBLE
|
|
The goals of the Open Font License (OFL) are to stimulate worldwide
|
|
development of collaborative font projects, to support the font creation
|
|
efforts of academic and linguistic communities, and to provide a free and
|
|
open framework in which fonts may be shared and improved in partnership
|
|
with others.
|
|
|
|
The OFL allows the licensed fonts to be used, studied, modified and
|
|
redistributed freely as long as they are not sold by themselves. The
|
|
fonts, including any derivative works, can be bundled, embedded,
|
|
redistributed and/or sold with any software provided that any reserved
|
|
names are not used by derivative works. The fonts and derivatives,
|
|
however, cannot be released under any other type of license. The
|
|
requirement for fonts to remain under this license does not apply
|
|
to any document created using the fonts or their derivatives.
|
