In windows cmd.exe, ^ is a special character so there is already a need
to type ^^/ instead of ^/. This is a common pitfall for Windows users.
In cmd.exe ^^/ would need to be typed as ^^^^/ which is getting a bit long.
When ^/ was introduced, this problem was already known but accepted.
It is not easy to find a syntax which does not overlap with something
already used by various shells on various operating systems.

Note that several relative URL notations were already defined for the
svn:externals property. You might want to avoid overlap with these and
perhaps try to find something that looks sufficiently different.
>From 'svn help ps':
The URL may be a full URL or a relative URL starting with one of:
../ to the parent directory of the extracted external
^/ to the repository root
/ to the server root
// to the URL scheme
^/../ to a sibling repository beneath the same SVNParentPath location
