KeyError: 260

[LittleApple-fp16]

neuralcloud/character seems lead to an unexpected error, is this a bug?
It appears on any version and os, but I've only recently discovered such of this.

>>> from gchar.resources.sites import get_site_tag
>>> get_site_tag('知更鸟','danbooru')

btw '雷电将军' does not raise this error
