after dumping the registered craft recipes using the same function as provided by the mtg_craftguide, many recipes were observed to have an itemstring containing escaped UTF sequences:

["homedecor:bed_kingsize 1 0 "\u0001palette_index\u000256\u0003""] = {
	"homedecor:bed_regular",
	"homedecor:bed_regular",
	"dye:pink"
},

["framedglass:steel_framed_obsidian_glass_tinted 1 0 "\u0001palette_index\u0002112\u0003""] = {
	"framedglass:steel_framed_obsidian_glass",
	"dye:blue"
},
["framedglass:steel_framed_obsidian_glass_tinted 1 0 "\u0001palette_index\u000288\u0003""] = {
	"framedglass:steel_framed_obsidian_glass",
	"dye:bright_blue"
},
["framedglass:steel_framed_obsidian_glass_tinted 1 0 "\u0001palette_index\u000264\u0003""] = {
	"framedglass:steel_framed_obsidian_glass",
	"dye:light_blue"
},
["unifiedbricks:clayblock 1 0 "\u0001palette_index\u0002137\u0003""] = {
	"default:clay",
	"dye:indigo_s50"
},
["unifiedbricks:clayblock 1 0 "\u0001palette_index\u0002113\u0003""] = {
	"default:clay",
	"dye:indigo"
},
["unifiedbricks:clayblock 1 0 "\u0001palette_index\u000289\u0003""] = {
	"default:clay",
	"dye:bright_indigo"
},

which likely means unifieddyes is storing metadata in the itemstring.

Still investigating root of cause and possible fixes
