Fonts in IE
If Polytonic Greek fonts are viewed in IE on a WinXP OS, then accented vowels are going to display as the missing glyph box. As you may know, I love Unicode. So I wonder if I could mention this little detail. span style="font-family:tahoma;" Put this little piece of code inside <> and place in front of your Polytonic Greek text and and there you are.
If what is posted is using combining diacritics it may still look a little wonky but at least it will be all there. More about combining diacritics here and here. If you are happy to have your Greek text display in Mozilla but not IE, then please ignore this post.
Update: Now that it is evident that I am not the only one that dislikes certain limitations in the Tahoma Polytonic Greek range, I wonder if this would work instead. Here is the Greek text in Palatino Linotype from GreekBible.com in precomposed text. I hope this is the UBS text. The site does not specify. This text has span style="font-family:palatino linotype;" in angle brackets at the beginning and /span in angle brackets at the end. And large size so you can see those nice little accents.
- καὶ μὴ μεθύσκεσθε οἴνῳ, ἐν ᾧ ἐστιν ἀσωτία, ἀλλὰ πληροῦσθε ἐν πνεύματι, λαλοῦντες ἑαυτοῖς [ἐν] ψαλμοῖς καὶ ὕμνοις καὶ ᾠδαῖς πνευματικαῖς, ᾄδοντες καὶ ψάλλοντες τῇ καρδίᾳ ὑμῶν τῷ κυρίῳ, εὐχαριστοῦντες πάντοτε ὑπὲρ πάντων ἐν ὀνόματι τοῦ κυρίου ἡμῶν Ἰησοῦ Χριστοῦ τῷ θεῷ καὶ πατρί, ὑποτασσόμενοι ἀλλήλοις ἐν φόβῳ Χριστοῦ. Αἱ γυναῖκες τοῖς ἰδίοις ἀνδράσιν ὡς τῷ κυρίῳ, Ephesians 5:18-22
Those missing glyph boxes are like a dropped stitch in knitting. I have to go back and pick them up every time. :-)
