Preferences
For object identifiers the char preferences are given by the following order:
char as regex | note |
---|---|
0-9 | |
a-zA-Z | |
_ |
|
- | |
/ | |
. | concatination, when / is not available, e.g. in file names |

In path names the "/" is used. If "/" cannot be used the general recommendation is to use the "." instead.
That also means the . and / are to be avoided inside ids, if possible.
