Two things learned the hard way while moving the build buttons. A shift glyph
written as a literal would have been mangled by MSVC 2017, which does not read
the sources as UTF-8 by default, and a PowerShell Get-Content/Set-Content
round-trip re-encoded a source file with a BOM and double-encoded em-dashes.
Screen-capturing the app window returns a blank client area because the capture
cannot read the QOpenGLWidget surface, which is easy to misread as a broken UI;
visual checks belong to the user.
