Deceitful Batman Challenge

look at the input field.

“Flag format: HTB{s0m3_t3xt}”

I got confused there too, but yeah you should be able to figure it out now.

Underscore - noted.
Flag format is in lowercase but the description says that “(The flag is in uppercase)”. So, what is the correct case?

I also tried to submit many variations of relevant words from Wikipedia but none of them worked so far. Am I supposed to try many variations for this challenge?

I tried to submit the following words in uppercase separated with ‘_’ (I only write the first letter and length for each word so not to spoil):
A4_N6
N6_A4
A4_W7_N6
A4_W7_N6_C9
A6_B6
B6_A6
A6_P10
A6_T8_C5_P10
… and many other

Update: I found that there is an ambiguity. I also tried word combinations with J5 but none of them worked as well.
