FreeMind stores unicode characters as XML character entities into mind map files.
Reading of UTF-8 encoded mind map files is supported to some extent; to be researched and documented.
Reading of UTF-32BE, UTF-32LE, UTF-8, UTF-16BE and UTF-16LE seem to be all supported provided the mind map starts with byte order mark (BOM).
Writing of UTF-8 is probably not supported; there was a feature request for this.
FreeMind does not seem to write any BOM natively.
Implementation
- Class FileReaderCreator in MindMapMapModel uses UTF-8 as the character encoding: 'return new UnicodeReader(new FileInputStream(mFile), "UTF-8");'
- The above class is instantiated in MindMapMapModel.loadTree(final File) method.
- Which is called from MindMapMapModel.load(File file).
- Class UnicodeReader determines the encoding from byte order mark (BOM), if any; it seems to take the passed-in "UTF-8" in case there is no BOM.
Links:
- MindMapMapModel.java, sourceforge.net
- UnicodeReader.java, sourceforge.net
Tracker items
- RC4 regression: incorrect viewing of UTF-8 map, bug, sourceforge.net
Limitations
- There is no or little support for XML declaration at the top of the mind map file; to be tested and clarified.
- Probably no writing in UTF-8, as per above.
