Note that a "workaround" is to use UTF-8, (and IDNA for DNS), although since that is both preferred and the common practice, it is difficult to describe that as a workaround ;-)

IE uses the Windows code pages. Use of code pages other than Unicode is discouraged and new code pages are not being added to Microsoft products. Romanian is correctly supported with UTF-8, and nearly all Romanian web content is correctly authored in UTF-8.

Domain Name support for Romanian is unrelated. Romanian Domain Names are properly supported by IDNA2003 and IDNA2008, which are both supported by Internet Explorer. The registrar's page linked to is also correctly encoded in UTF-8. The registrar's policies are up to each registrar, however the standards allow correct registration of Romanian IDNA2008 names. has some information about IDN.

My test page encoded as iso-8859-16 is located here: <a href=""></a>

This webpage shows all iso-8859-16 characters <a href=""></a>.

I have noticed that the following webpage is being displayed
differently by Internet Explorer 8 when different languages are set in "Regional and Language Options",
"Language for non-Unicode programs".

When "Romanian" language was set, the above webpage displayed T/t-Cedilla and S/s-Cedilla
characters instead of T/t-Comma Bellow and S/s-Comma Bellow, as if iso-8859-2 was set.
When "English (United States)" language was set, the place for T/t-Comma Bellow and
S/s-Comma Characters was filled with characters from iso-8859-1.

Internet Explorer should display iso-8859-16 pages just like all the other web browsers do.

The Romanian Top Level Domain Registrar ( does not allow Romanian diacritics in Romanian domain names partially due to the lack of 8-bit proper Romanian encodings (ISO-8859-16)

All the other Windows browser makers support ISO-8859-16 encoding, only Internet Explorer doesn't, but Internet Explorer has a bigger market share.

Microsoft should not hold back proper Romanian Internet user experience.
