In Data Cloud segmentation, the 'Is Equal To' operator performs a case-insensitive exact match on the specified string value. It does not normalize or ignore diacritics (accent marks). Therefore, a filter for 'San José' will match any entry where the characters are exactly 'S', 'a', 'n', ' ', 'J', 'o', 's', 'é', regardless of their case. This means it will find 'San José' and 'san josé', but it will not match 'San Jose' because the 'é' is treated as a distinct character from 'e'.

A. This describes the behavior of a 'Contains' operator, not 'Is Equal To'. The match must be exact, not partial.

B. This is incorrect because the filter is case-insensitive, but it incorrectly ignores the required accent mark on the 'é'.

C. This is incorrect because it is case-sensitive (wrongly suggesting only 'San Jose' would match) and also ignores the required accent mark.

1. Salesforce Help. (2024). Segmentation Filter Operators. Section: "Text Operators". The documentation specifies that the "Is Equal To" operator is case-insensitive for text values.

2. Salesforce Developer Documentation. (2024). Segmentation API. The behavior of filter expressions in the underlying API confirms that string equality is case-insensitive but character-specific, meaning diacritics are not normalized against their base characters.
