Special character problems
Users may import 'special characters' such as the degree symbol or the micro
symbol (Greek mu) into data packages, especially by copying from MS word or
other sources which use custom character sets. These special characters can
cause various problem when stored in XML documents because they are not unicode
and because one cannot determine just what characted set they originated in.
When pasting in degree and mu symbols on Windows, the display looks fine until
the document is saved locally, If Morpho is then exited and re-opened, the
document with the special characters does NOT appear in the list of local
documents. The problem is:
java.io.UTFDataFormatException: Invalid byte 1 of 1-byte UTF-8 sequence
caused by the coding of the deg symbol (and the mu symbol is missing from the
Previously a special 'normalize' method was used to handle the strings used in
data packages. The problem with Morpho 1.5 is that the DOM routines used handle
much of the character/entity translations automatically - e.g. '&' automatically
becomes '&' and is converted back to '&' when displayed.
