The title is U+ = %

U+ stands for Unicode notation. The result of each Unicode number will give a character that looks like the % sign.

U+2105 U+2105 U+2101 translates to: ℅℅℁

U+2100 U+0025 U+2106 U+214D U+2100 U+2105 U+2106 U+2101 translates to: ℀%℆⅍℀℅℆℁


"\/\/\" denotes the zig-zag direction where the letters in "℅℅℁" are read.

This reads: cocoas

"________" denotes the bottom line direction where the letters in "℀%℆⅍℀℅℆℁" are read.

This reads: couscous

"‾‾‾‾‾‾‾‾" denotes the top line direction where the letters in ℀%℆⅍℀℅℆℁ are read.

This reads: aocAacca

aocAacca is the Vigenére key for irgoggpy. It decodes to: ideogeny

It is a 1x1 pixel image. Open the .png image in a text editing software of your choice, online or offline. Inside the image at the end of the file, there is a chunk of binary:

The title of the paste is #######(#) meaning: 0000000>0<

The title of the 1x1 image is called 8bit-LSB.

To find the hidden message in this chunk of binary, separate it into 8 bits and take the LSB (least significant bit) of each 8 bit binary string. (To put it simply, only record every 8th digit.)

The duck has been found.

U+₁₆ was meant to denote Unicode + base 16 (hexadecimal).

#| translates with hexadecimal to 23 7c (with no padding).

U+237c is the the Unicode character: ⍼

Based off the format, this character is titled: right angle with downwards zigzag arrow

So the password for the weekly was: right angle with downwards zigzag arrow
