Space contraceptive

This is also a classic example of an incompletely implemented line wrapping logic commonly seen in games. While most languages use spaces to split words in one way or another, there are languages like Chinese, Japanese, and Thai that generally doesn’t use spaces in a sentence.

Line wrapping logic that expect words to be separated by spaces will treat an entire piece of text in these languages as one word. In the example, the only space in the description text is in the “20% max” part, causing the algorithm to treat the text as two long words. In order not to break the “words”, it decided to shrink the font size in order to fit the “word” in one line, causing the text to be barely readable.
