Hi there,

here's a patch for the Calendar 0.9.10 product.

This version allows people to define their own
day or month names instead of the default 
english names.

This is very useful if you want to setup a 
web calendar in another language than English.

In French, some month names contain accented letters,
represented in HTML by character entities like é
for example.

The Calendar product doesn't cut the month names
correctly in regard to these entities, especially
in week mode when a week was between two months.

Here's a patch to correct the problem.

hope this helps.

bye,
Jerome Alet
