Character Sets

Character Sets

A character set contains expressions that identify specific characters and character ranges. You can use character sets in Labeler transformations that use character labeling mode.
Character ranges specify a sequential range of character codes. For example, the character range "[A-C]" matches the uppercase characters "A," "B," and "C." This character range does not match the lowercase characters "a," "b," or "c."
Use character sets to identify a specific character or range of characters as part of labeling operations. For example, you can label all numerals in a column that contains telephone numbers. After labeling the numbers, you can identify patterns with a Parser transformation and write problematic patterns to separate output ports.
