MC crashes with too wide characters in signs

Mc crashes when a sign containing a character wider than the sign is placed.

JSON that defines character

{
 "providers": [
 {
 "type": "bitmap",
 "file": "sample:sign_overlay.png",
 "ascent": 31,
 "height": 48,
 "chars": [
 "\ue000"
 ]
 }
 ]
}

sample:sign_overlay.png is a 24x12 texture

Command to get sign

/give @p minecraft:oak_sign{BlockEntityTag:{Text3:"{\"text\":\"\",\"color\":\"white\"}"}} 1

NOTE:
It does not crash if the block is placed prior to applying the resource pack
