Euclid Symbol font problems in InDesign

@Tia22176807c222   I'm confused by the Unicode numbers in your post.

Unicode 00b4 is not the multiplication x character: it's the acute accent mark. See https://util.unicode.org/UnicodeJsps/character.jsp?a=00b4&B1=Show 

And Unicode 00d7 is not a multiplication dot; it's the multiplication x symbol. https://util.unicode.org/UnicodeJsps/character.jsp?a=00d7&B1=Show

I do not own a version of the Euclid font so I can't verify whether it has the characters you want to begin with. Most fonts do not have a set of math symbols in them, other than the basics, and multiplication x is not a common symbol on most fonts.

When a particular Unicode symbol isn't available on a font, applications often swap in a dot, circle, tofu block, or space for the missing glyph.

Suggestion:

• Verify the Unicode glyph codepoints (their numbers) for the symbols you want. Use the math symbol charts at https://www.unicode.org/charts/ (scroll to the second page for math).
• And then check your Euclid fonts in a font manager program that shows its complete character set. (You can use InDesign's Glyph panel to view the complete set.) Check to see if your version of Euclid actually has the glyphs you want.
• Make sure the EPS files have their fonts embedded into them. That's usually done in the source program when the EPS is exported.

Good luck!
