how to avoid symbol or icon

[kurikabocya]

I want to avoid symbol or icon.
EAST detect symbol or icon as text mistakenly.
Reading icdar.py
if label == '*' or label == '###':
text_tags.append(True)
else:
text_tags.append(False)

Please teach me when training EAST,

if ### is used as lable on a line which is surrounding symbol or icon.
does EAST regard it as symbol or icon
and does not detect it as symbol ?
