\usepackage[polutonikogreek]{babel}
and the \textgreek command like \textgreek{<αμαρτία}
I can easily insert aspirate in front of the first alpha of the word αμαρτία . But I cannot copy the resulting text from pdf output because has strange characters like martÐa. My next effort was to use \usepackage{xstring}
and \StrSubstitute to substitute >α with ἀ in a greek passage( I used \StrSubstitute{\text}{>α}{ἀ}[\text
] to substitute alphas in \text). But there are many rules for alpha, eta and other letters(about ~170 rules) so my method is very time consuming when I have a big text(5 to 10 pages)! My questions are:
1) Is it possible to have a simple and fast way to write greek using common symbols like >, <, ~ | of polutonikogreek (babel ) to insert accents and other symbols in LaTeX and XeLaTeX?
2) I can copy the resulting text from resulting pdf output without any problem(what you see is what you copy..)
3) The method will respect the polytonic greek hyphenation rules.
Thank you in advance!
