cExpression

Specifies the character expression for which LENC(В ) returns the number of characters.

Numeric

LENC(В ) is designed for expressions containing double-byte characters. If the expression contains only single-byte characters, LENC(В ) is equivalent to LEN(В ).

LENC(В ) returns the number of characters in a character expression or memo field containing any combination of single-byte and double-byte characters.

This function is useful for manipulating double-byte character sets for languages such as Hiragana and Katakana.
