# kTECFallbackTextLengthFixBit

## Declaration

```occ
kTECFallbackTextLengthFixBit = 1
```

## Discussion

Discussion This is set if the Unicode Converter has a bug fix to use the source length (srcConvLen) and destination length (destConvLen) returned by a caller-supplied fall-back handler for any status it returns except kTECUnmappableElementErr. Previously it honored only these values if noErr was returned.
