Habitat Sign Escape and Graphical Character Codes

These are the character escape codes that you may use in an ASCII byte array to represent non-printing characters and Habitat sign formatting symbols:

Character	Description	ASCII code	hex
\n	newline	10	x0a
\t	horizontal tab	?	?
\b	backspace	?	?
\r	carriage return	13	x0d
\f	form feed	?	?
\e	escape	?	?
\\	backslash	109	x4D
'	apostrophe	39	x27
"	quote	34	x22
\	(backslash-space) half space	128	x80
\#	double space	143	x8f
\+	increment text width	129	x81
\-	decrement text width	130	x82
\(	increment text height	131	x83
\)	decrement text height	132	x84
\h	half size characters	133	x85
\R	sign carriage return	134	x86
\d	move half character space down	139	x8b
\i	shift to inverse video	140	x8c
\>	cursor right	135	x87
\<	cursor left	136	x88
\^	cursor up	137	x89
\v	cursor down	138	x8a
\c	CONTROL-c (where c is any character)	1-26	x01-x1a
\ddd	arbitrary byte (where ddd is one, two or three octal digits)	ddd10	ddd16
\xhh	arbitrary byte (where hh is one or two hexadecimal digits)	hh10	hh

As an example, lets say your original text is represented as this in your griddle file where you'll encounter these escape characters:

• GRI text: "\hOrder\h of the \hHoly\h \hWalnut "
• is the same as: "\x85Order\x85 of the \x85Holy\x85 \x85Walnut "

Strings are messy in JSON and Java, so we've got a special attribute name for these bytes on signs: "ascii":[bytes], so the same sign text is stored in the database as:

• "ascii":[133,79,114,100,101,114,133,32,111,102,32,116,104,101,32,133,72,111,108,121,133,32,133,87,97,108,110,117,116]
• NOTE: RDL files already represent the sign text as byte codes and can be used as they appear in the file.
  • No need to decode them using this table.
