Unicode hex value checks in cmap tables (fonts)

hexcheck.py

tt = TTFont(fontpath)
cmap = tt.getBestCmap()

# now the integers are keys in the cmap object and can be used to compare against hexadecimal values for presence in a font

test_list = (hex1, hex2, hex3,...)

# how to split hex ranges to individual hex codes
# e.g., 0x0020-0x0028
for x in range(0x0020,0x0028):
	print(hex(x))

for codepoint in test_list:
    if int(codepoint) in cmap:
    	print(True)
    else:
    	print(False)
