[htmltmpl] Escaping unicode

[Tobias N. <tn...@mo...>]

Hi!

I'm using HTML::Template to generate RTF-documents which works pretty
good with plain ASCII. But since with RTF Unicode characters have to be
escaped (like \u0123, Unicode::Escape exists for this), I have to
either escape it before I feed it to HTML::Template or I have to
convince H::T to escape it on-the-fly. The filter option sounds
promising, but it touches the template before the tags are parsed.

For the data to be escaped before feeding it to H::T, I'd have to add
a lot of code, therefore I'd like to avoid this approach. Is there any
way I can tell H::T to escape Unicode data I feed to it with param()?
If not, then the next best thing would be to create a patched version of
H::T for my purposes with a method like param_escape() or sth like that,
right?

Best regards!
Tobias
