--------------------------------------
Summary: Extend StringEscapeUtils with escapeFilename() method
Key: LANG-918
URL: https://issues.apache.org/jira/browse/LANG-918
Project: Commons Lang
Issue Type: Improvement
Components: lang.*, lang.text.*
Reporter: Olivier Vierlinck
Priority: Minor
It would be nice if StringEscapeUtils could take any string (include with
backslash, forward slash, tab, CR, LF, extended unicode chars,...) and turn it
into a valid filename, escaping the 'invalid' characters.
Implementation might be OS-dependent or simply escape all characters which are
invalid in at least one of the major OS (Unix/Windows/Mac)
Rationale: it is quite common to receive uncontrolled text (from Web form, from
mail parsing, ...) and need to turn it into some part of file/folder name (to
create some workspace, archive data,...) which 'ressemble' (and +/- human
readable) to the original free text.
Could be very similar to escapeHtml(): replace each invalid char by
%HexCodeOfChar - only the list of 'invalid chars' would be different.
