.. _DXF File Encoding:
DXF File Encoding
=================
DXF R2004 and prior
-------------------
Drawing files of DXF R2004 (AC1018) and prior are saved as ASCII files with the encoding set by the header
variable $DWGCODEPAGE, which is ``ANSI_1252`` by default if $DWGCODEPAGE is not set.
Characters used in the drawing which do not exist in the chosen ASCII encoding are encoded as unicode characters with
the schema ``\U+nnnn``. see `Unicode table`_

DXF R2007 and later
-------------------
Starting with DXF R2007 (AC1021) the drawing file is UTF-8 encoded, the header variable
$DWGCODEPAGE is still in use, but I don't know, if the setting still has any meaning.
Encoding characters in the unicode schema ``\U+nnnn`` is still functional.
