support for non-Asian languages is supported for text styles that use SHX fonts
with Big Fonts disabled. (The SHX font must define the required characters.)
Multiple-language support does not exist in some earlier releases of AutoCAD.
For example, when you save a file to AutoCAD 2000 format, the contents of
multiple-language multiline text may be corrupted. This problem is more
likely to happen when you open and save a drawing on an operating system
with a system language setting that differs from the system in which the
drawing was last saved.
NOTE Drawings that include external references (xrefs) to drawing files saved in
earlier releases also have the limitations described above.
Save Drawings to Previous Drawing File Formats
You can save a drawing in a format compatible with previous versions of the
product.
You can save a drawing created with the current release of the program in a
format compatible with previous versions. This process creates a drawing with
information specific to the current release stripped out or converted to another
object type.
If you use the current release to open a drawing created with a previous release,
and you do not add any information specific to the current release, you can
then save the drawing in the format of the previous release without loss of
data.
NOTE
To use files with AutoCAD Release 12 or AutoCAD LT Release 2, save the
drawing using the AutoCAD R12/LT2 DXF option.
If you need to keep a drawing created in a previous release in its original
format, either mark the file as read-only, or open it in the current release and
use the File Type options in the Save As dialog box to save it in its original
format.
Because saving a drawing in an earlier release format may cause some data
loss, be sure to assign a different name to avoid overwriting the current
drawing. If you overwrite the current drawing, you can restore the overwritten
version from the backup file (filename.bak) that is created during the saving
process.
