I'm a Blessed user, and recently, when I tried to find out the contents of the term.bold() function, I got this output: \x1b[1m\x1b(B\x1b[m

I understand what \x1b[1m and \x1b[m do, but what does \x1b(B do? I tried printing it, but it doesn't seem to do anything at all.

Thanks in advance!

The control sequence \x1b(B selects the default character set ASCII. See XTerm Control Sequences:

ESC ( C   Designate G0 Character Set (ISO 2022, VT100).Final character C for designating 94-character sets.  In thislist, 0 , A  and B  apply to VT100 and up, the remainder toVT220 and up.  The VT220 character sets, together with thePortuguese character set are activated by the NationalReplacement Character controls.  The A  is a special case,since it is also activated by the VT300-control for BritishLatin-1 separately from the National Replacement Charactercontrols....C = B  -> United States (USASCII).

That is provided just in case the terminal was set to some other character set, e.g., line-drawing. Blessed is probably retrieving this as part of \x1b(B\x1b[m, e.g., in

    normal = tigetstr('sgr0')
