IE 10 not rendering Japanese correctly

I recently discovered an issue with IE10. We have a web page that displays English text beside a translation in Japanese. Some of the Japanese characters display as squares. In the view source page all characters are correctly rendered. The database also has the characters correctly rendered. The unusual part is that when I block the characters with the cursor they convert to the correct characters.

IE10 I believe has a bug.

Anyone having similar issue or know of a fix? Checked all language settings, regional settings, browser font settings and many other tests. Nothing corrects this issue.

This issue was related to a dual byte character which some fonts and windows applications will support.

Some older fonts may use a two hex character representation to present a single character. Some fonts support this and some do not.

In this case the characters at issue were the following…..

ジ

シ and ゙

The latter two which I think are special characters that combined are intended to represent ジ.

The Unicode Standard from the Unicode ISO web site table defines them like so…..

Decimal Character HEX Name

12472 ジ 30B8 KATAKANA LETTER ZI

12471 シ 30B7 KATAKANA LETTER SI

12441 っ゙ 3099 COMBINING KATAKANA-HIRAGANA VOICED SOUND MARK (combined with small tu (っ))

So some fonts use 12471 + 12441 to make 12472. This is what I found. But the actual string has 12471 + 12441 and not 12472 or the hex: 0x30B7, 0x3099 and not 0x30B8.

Any time a font being used does not support this binding, a box is displayed. The challenge is that it may be as simple as someone creating a birthday card using a non-compliant UTF8 font that could cause a PC to not allow the character to display correctly.
