Remove invisible U+200E unicode character from yabai query

[mrala]

Description

If an app has an invisible U+200E character, it will not match the app name defined in app-icons.js.

• Fixes WhatsApp icon not being used #405

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

• Validated app names are dropping the U+200E character without affecting other unicode characters.

❯ queryTitle=$(yabai -m query --windows --space 1 | jq '.[].app')
❯ echo $queryTitle
"‎WhatsApp"

# get the ASCII value of the unicode character
❯ echo $queryTitle | hexdump -C
00000000  22 e2 80 8e 57 68 61 74  73 41 70 70 22 0a        |"...WhatsApp".|
0000000e

# compare to expected string without unicode character
❯ echo \"WhatsApp\" | hexdump -C
00000000  22 57 68 61 74 73 41 70  70 22 0a                 |"WhatsApp".|
0000000b


❯ echo $queryTitle
"‎WhatsApp"

# get number of bytes with string that contains hidden unicode character
❯ echo $queryTitle | wc -c
      14

# remove UTF-8 hex (e2 80 8e)
❯ echo $queryTitle | sed "s/\xe2\x80\x8e//g" | wc -c
      11
# compare number of bytes to string without unicode character
❯ echo \"WhatsApp\" | wc -c
      11


# does not affect other unicode characters, test with Chinese name for Finder
❯ echo $'\U8BBF'$'\U8FBE'
访达
❯ echo $'\U8BBF'$'\U8FBE' | wc -c
       7
❯ echo $'\U8BBF'$'\U8FBE' | sed "s/\xe2\x80\x8e//g"
