It looks like a [ space due to the character width, but it's actually a different symbol entirely. It is 【, a single full-width character commonly used in CJK contexts.

before: 【 (U+3010, CJK Left Black Lenticular Bracket)
after: [ (U+005B, ASCII Left Square Bracket)

In this case, the 【 broke the Markdown syntax, causing the statement to be parsed as plain text instead of the expected link.
