I'm using Tex Live, under Ubuntu 11.11, and Texmaker to create LaTeX source files. Sometimes I edit these files with Krviewer from Krusader, but I pay attention to use the input encoding latin10 (or ISO 8859-16). My layout keyboard is Romanian standard, which correctly produces Romanian diacritics with comma below (as in latin10).
In the document preamble I use
\usepackage[romanian]{babel}
\usepackage[latin10]{inputenc}
\usepackage[T1]{fontenc}
The output pdf file correctly renders the characters, with comma below, but thy are not find by the search engine and they are not copied correctly to the keyboard. For example: if I copy the word știință it will paste s , tiint , ă, this being the reason why it wont't be found by the search engine of the pdf reader.
Any suggestions, please?
