If you use Arial font in Igor6 on MacOS 10.12 (Sierra), Igor displays "unicode conversion error" instead of the correct text in graphs.

This affects both the English and Japanese versions of Igor6.

WORKAROUNDS

1. Purchase an upgrade to Igor7 which does not have this problem.

2. Use a different font.

3. Drag the Arial.ttf font file from /Library/Fonts to some other folder for safe keeping and restart your machine. Igor6 will use Geneva in place of Arial.

4. Drag the Arial.ttf font file from /Library/Fonts to your desktop and restart Igor. Igor will display blank text for Arial. Quit Igor and drag Arial.tff back into /Library/Fonts and restart your machine. Arial now works correctly in Igor. This workaround may not be reliable or durable, though I have not seen it to fail in limited testing.

Workaround #4 works for ASCII characters only. It does not work for non-ASCII characters (accented characters, math symbols, ...). For non-ASCII characters, you need to use workaround #1, #2 or #3.

5. Drag the Arial.ttf font file from /Library/Fonts to some other folder for safe keeping. Replace your Arial.ttf file in /Library/Fonts with an Arial.ttf file from C:\Windows\Fonts on a Windows machine and restart your machine. This workaround works for ASCII characters only. It does not work for non-ASCII characters (accented characters, math symbols, ...).

Workaround #5 works for ASCII characters only. It does not work for non-ASCII characters (accented characters, math symbols, ...). For non-ASCII characters, you need to use workaround #1, #2 or #3.
