Convert HTML-escaped strings to plain Unicode/ASCII

[Allectict]

is there a Java/Android way to convert HTML-escaped strings (such as \[code\]Ö\[/code\] or \[code\]ß\[/code\]) back to their ASCII/Unicode representations (such as \[code\]?\[/code\] or \[code\]?\[/code\])?I of course do not want to do a simple string-replacement and try with just every HTML-escape-sequence that exists, I'd guess there is a ready-to use solution?Thanks!
