Cédric Damioli commented on JCR-3443:
-------------------------------------
a) Do you suggest someting like "rep:normalize" ?
b) I did not actually tried to implement a collation algorithm, which certainly
depends on locales, but instead a normalization algorithm
(http://www.unicode.org/reports/tr15/) which do not depend on locales.
I could have implement it using java.text.Normalizer.normalize(), followed by
the removal of non ASCII-characters, but this is roughly equivalent to the more
easier Unicode-to-ASCII method I found in the Lucene code.

> Properties containing non-ASCII characters are not well collated in query
> results
> There's only two allowed functions so far in XPath (fn:lower-case and
> fn:upper-case). There exists the equivalent LOWER and UPPER in SQL
> I propose to add a fn:normalize (resp NORMALIZE) function giving expected
> results
