PO Localization

When you localize PO file with Sisulizer add the original .pot file into Sisulizer project. If you do not use .pot files select the original .po file. When building the project Sisulizer creates the localized PO file. Sisulizer also compiles the created PO files into binary MO files.


Each PO/POT file contains header value that contains one or more fields.

msgid ""
msgstr ""
"Project-Id-Version: PACKAGE VERSION\n"
"Report-Msgid-Bugs-To: \n"
"POT-Creation-Date: 2005-05-07 10:20+0200\n"

"Language-Team: LANGUAGE <>\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=CHARSET\n"
"Content-Transfer-Encoding: 8bit\n"

Content-Type Character set Write "Content-Type: text/plain; charset=CHARSET\n"
Content-Transfer-Encoding Bits per character Write "Content-Transfer-Encoding: 8bit\n"
