There's no single function for this, but (depending on how the lines were generated) all the information is available. TLF has two basic ways of generating text lines, one using the ContainerController, and one using the TextLineFactory. If you have a standalone TextFlow, it has a IFlowComposer, which has a list of TextFlowLines. Each TextFlowLine has an absoluteStart, which is the text index of the start of the line, and a textLength.

If your TextFlow is part of a TextContainerManager, or if the lines were generated from the TextLineFactory, it gets a little more complex. You can get access to the TextLine using the TextContainerManager's getLineAt function, but the TextLine is by then disconnected from the TextBlock where the Unicode text values are stored. If the TextLines are in order, and start at the start of the flow, you can start at 0 and sum through using the TextLine's rawTextLength property.

Hope this helps,
