# ECISegment Class

The `ECISegment` class represents the Extended Channel Interpretation (ECI) information within a barcode. Each ECI segment specifies the character encoding used for a portion of the decoded bytes. The charset names follow the IANA character set registry (e.g. "UTF-8", "ISO-8859-1").

**Remarks**

Introduced in Dynamsoft Barcode Reader SDK version 11.4.1000 and Dynamsoft Capture Vision version 3.4.1000.

## Definition

*Module:* dbr
