Hi!

On Windows 7 we have Puppet 4.2.x and, in order to deal with accented
characters commonly found in registry key DisplayName, we use unicode
escape sequences in our manifests such as "\u00FA".

However, on Windows XP,  we couldn't install Puppet 4.2.x so we use
3.8.x instead. When running the same manifest with escape sequences,
Puppet complains: "Unrecognised escape sequence '\u' in file ...".

Have you tried using 3.8.x with parser=future turned on? That would give you support for \u the same way as in puppet 4.x.

Puppet 3.8.x documentation states that it "treats strings as sequences
of bytes. It does not recognize encodings or translate between them, and
non-printing characters are preserved."

Yes, when you get the waring for \u, it means there will be a literal backslash and a literal u in the resulting string. (That is with the regular parser since it (as it says) does not support the \u escape for unicode chars).

So, how can I deal with software that have accented characters in their
DisplayName? Assuming that registry's encoding is the same on WXP and
W7, I could probably make it work by using Puppet 4.2.x on Windows XP,
but I just don't know how to install it successfully.


Use puppet 3.8.x (latest) as noted above. The other approach (ugly, and horrible work around) is to simply copy/paste the actual character into the source file, but that is not guaranteed to work for all characters.

Hope that helps
