I started to use librecad 2.0.4 on jessie debian at work and 2.0.9 on gentoo-testing at home.
Before that I was used some kind dwg map by autocad with greek fonts for roads and used the find text ability and zoom-to to see where a specific road is located. The map was large. 86756 entities with 33344 texts counted by autocad. With librecad i had not greek fonts on proper (utf-8?) keys. So i rearranged the greeks.lff to get these in proper, for today, keyboard keys and designed a final 's' too. I could not have accents because there had to be two strikes. For example ';+e'. This file is http://jmp.sh/ipaYXod . In order to have greek at unicode i merged greeks-mine.lff to unicode.lff and added the accent symbols. This file is http://jmp.sh/iPEr80g and copied at /usr/share/librecad/fonts/ (Feel free to rename and use them as you like)
Then in autocad i changed all fonts to style 'standard' and saved map as dxf 2000. I opened the dxf with librecad and saved it. Of course autocad don't open the librecad saved file again, considering it 'incomplete'. Librecad put 'standard' font to texts (choosing the style name?). So in terminal i gave the following command.
sed -i 's/standard/unicode-mine/g' newlibrcadfilemap.dxf (Changing all text fonts by one command)
Now i see greek fonts in map with librecad.
But file is large and every action is slow as if all map, not only display window, is redrawed every time even in draft mode (there is no hatch patterns on map). I noticed that librecad uses only one cpu. On gentoo i have 4 cpu s and on jessie 2. With librecad a cpu goes to 100% usage and others below 25%. If more cpu s would be used, performance would be better.
Of course I no longer have the search text ability (i put it here as a possible request) and so I will not use librecad for that large file.
I will try but I m not sure if I will follow this post because i am not used or use other mailing lists.  
I just wanted to share my experience so far.
Thank you
