Weirdness with account title in register window

A little while back, I changed all of the account names in my Quicken 
file to include an em dash (using ALT+0151 on my keyboard) as opposed to 
a regular dash because it just looked better when looking at the account 
names in the account bar.

Today I was in Quicken and noticed that any account name that had the em 
dash in its name had been truncated in the upper left of the register 
window, with the last 3 characters of the account name being replaced 
with an ellipsis (...). Name length did not appear to be a factor since 
it happened even with accounts containing only ten characters, including 
spaces. I started changing the em dashes back to regular dashes and the 
full account names then appeared in the register window.

Has this happened to anyone else and does anyone know *why* this happens?
