The goal of the text is to document already known bugs and how to work around it.
Problem is that yast2-core in parser already expand some escaped characters which cause wrong translation of them. Characters that have problem are
"\a", # alert
"\b", # backspace
"\e", # escape
"\f", # FF
"\r", # CR
"\v", # vertical tab
Workaround is to grep ycp sources for all occurences of these rare characters and manually fix it after translation.
Include files conversion has hard-coded path to include file. If it is not used then generated include file is not correct and it will not work.
Workaround is to always run y2r in module root path and specify whole include file name like src/include/my/include.ycp
