"You selected a single-byte font to replace a double-byte font" when replacing a Japanese font

Symptoms

Consider the following scenario. You open a Microsoft PowerPoint 2010 presentation that contains Japanese font sets. On the Home tab, in the Editing group, under Replace, you click Replace Fonts. In the Replace drop-down list, you select a Japanese font that you want to replace. You select a different Japanese font in the With drop-down list. Then, you click Replace.

In this scenario, the font is not replaced. Additionally, you receive the following error message:

You selected a single-byte font to replace a double-byte font. Please select a double-byte font.

Cause

This issue occurs if the following conditions are true:

• The Japanese font that you want to replace is not installed on your computer.
• This Japanese font is a single-byte font.

When these conditions are true, you cannot replace the font, and you receive the error message.

Workaround

Method 1: Manually replace the font

To work around this issue, you can locate each text object that uses the font that you want to replace, and then select the text. Then, on the Home tab, in the Font group, on the Font drop-down list, select the font that you want to replace the old font with.

Method 2: Replace the font on a computer that has the font installed

To work around this issue, you can either install the font that you want to replace, or you can replace the font in the presentation on a computer that has the font already installed.
