Description
What it does
Warns about U+00A5 or U+20A9 followed by an escape character (x, n, r, t, u, 0) or itself.
Categories (optional)
- Kind: suspicious
Doing so suggests the intent to actually use U+005C (\) instead. When using Windows in Japanese locale, U+005C is rendered as a Yen sign. When using Windows in Korean locale, U+005C is rendered as a won sign.
Drawbacks
None.
Example
print!("Hello¥n");
Could be written as:
print!("Hello\u{A5}n");
or what was probably intended:
print!("Hello\n");

Research direction
