Hi
Using a ‘special’ character in any field within Legacy’s own
database should not cause any issues, unless Legacy itself is putting limits in
place.
However, using a name, valid as a field within Legacy, as part of a file name
within Windows can could issues since they must be constrained by the limits
within Windows. This is from the Microsoft website
1. Use any character in the current code page for a name, including
Unicode characters and characters in the extended character set (128–255),
except for the following:
a. The following reserved characters:
i.
< (less than)
ii.
> (greater than)
iii.
: (colon)
iv.
" (double quote)
v.
/ (forward slash)
vi.
\ (backslash)
vii.
| (vertical bar or pipe)
viii.
? (question mark)
ix.
* (asterisk)
b. Integer value zero, sometimes referred to as the ASCII NUL character.
c. Characters whose integer representations are in the range from 1
through 31, except for alternate data streams where these characters are
allowed.
d. Any other character that the target file system does not allow.
The problems originally occurred when the filename does not match the
‘traditional’ US naming standards, based on ASCII 32-127 characters sets. You
then become dependent on limitations built into the operating system, ZIP
software etc. and on the current code page in use. Changing the code page can
result in value of text and filenames to change. Strictly, the value does not
change but the visual display of it may – that was always an issue 20-30 years
ago, but should not be now.
Also be aware that there is a limit within Windows on the length of a file name
and path to a maximum of 256 characters. This seems to being resolved on the
latest updates to Win 10. It is also interesting that the filename and path are
stored as Unicode character sets, which should enable the use of any Unicode
character in a file name. The IJ is a single character, Unicode 0132 defined as
LATIN CAPITAL LIGATURE IJ, and Unicode 0133 is the lower case version of it.
Always with Unicode character sets, you need to be sure that the software
supports it and that the fonts know how to show it. That should not be an issue
now, especially since web addresses are now supporting Unicode character naming.
Certainly, I have just created, in Win 7, a file named IJ.txt, containing IJ as
its text, and created a ZIPped version of it with IZARC.

Hi William,
Just backed up Legacy files using Legacy internal backup, all OK.

My guess is using some special characters in Legacy may cause problems when
backed up to a ZIP file within the software. I get error messages when I ZIP
files in Windows then have to go back into the offending file to fix it because
it has a special character Windows doesn’t like.

In Dutch the ij isn't a special character you just type the i and the j. It's a
long time ago I have seen a Dutch keyboard with a separate letter ij. Most
Dutch use the English International keyboard.

How do I add a special character in a surname.
In Dutch a character can be either a “y” or “ij”.
Entering the “y” is no problem but how do I create the “ij” as a special
character?
Thanks in advance.
Ciao
