TEncoding not present in d7. Tell us what your real problem is. UTF7 sounds unlikely. – David Heffernan Sep 21 '11 at 11:27

i am reading a exe in C# and transferring it to delphi application and want to write data to a file. but some encoding problem is there. – Vinamra Bhantagar Sep 21 '11 at 17:53

I don't know what reading an exe in C# means. – David Heffernan Sep 21 '11 at 18:08

Oh there IS something called UTF7. Reversed my own edit. – Warren P Sep 22 '11 at 14:22

The SysUtils.TEncoding class is not available in D7. Use the Win32 API MultiByteToWideChar() and WideCharToMultiByte() functions instead, specifying CP_UTF7 as the codepage.

This one is correct Vinamra. Either fix your question, delete it, or accept this answer. I still think you're confused and you want UTF8, not UTF7. – Warren P Sep 22 '11 at 14:24

TEncoding was introduced in Delphi 2009. You should upgrade to a newer version of Delphi, such as XE.

Yes, but it is inconvenient. By the way, are you sure that you really want UTF7 and not UTF8? – Andreas Rejbrand Sep 21 '11 at 09:31

Ask about that in a new question, Vinamra. It's certainly possible to convert byte buffers to a UTF-7 encoding, but the comments for *this* question are not the appropriate place to discuss it. This question is specifically about TEncoding, not UTF-7 conversions. – Rob Kennedy Sep 21 '11 at 14:00
