Control Character Display

ASCII control characters are chars with the numeric value of [0-31]. They are meant for control operations such as back space, bell, escape, etc ... They are not textual operations and have no character associated with them. In a normal Visual Studio editor they are invisible and lead to confusing error messages.

VsVim will display ASCII control characters in the same way as gVim does. By using the ^B notation where ^ indicates a control character followed by the control code letter

This behavior can be disabled by toggling the vsvim_controlchars setting

:set novsvim_controlchars

After which the control characters will have the default display of nothing

The color which displays the control characters is configurable via the Visual Studio Fonts and Colors page. The name of the color is 'VsVim Control Character'
