public StringBuilder labelToASCII(CharSequence label, StringBuilder dest, IDNA.Info info)

Implements abstract com.ibm.icu.text.IDNA.labelToASCII.

Doc from com.ibm.icu.text.IDNA.labelToASCII.

Converts a single domain name label into its ASCII form for DNS lookup. If any processing step fails, then info.hasErrors() will be true and the result might not be an ASCII string. The label might be modified according to the types of errors. Labels with severe errors will be left in (or turned into) their Unicode form.

Parameters
label:CharSequence

Input domain name label

dest:StringBuilder

Destination string object

info:IDNA.Info

Output container of IDNA processing details.

Returns:StringBuilder
