Ahhh... I thought the n-dash was to be used all over, except on hyphenated words and in the start of sentences and middle of sentences.
Maybe the LT suggestion should state the ranges text:
"the half-dash (n-dash), should only be used to indicate numerical ranges or time ranges. "
(and just use this text in the English version).
This would make it clear to everyone
Ahhh.. right now I am about to replace all occurrences in the medical process document.
I have all medical documents scanned and inserted into that ODT, an ~300 MB ODT at the moment (it takes long to edit it, since this machine only has 4 GB RAM).
