I was reading the thread "glyph selection for Unicode in browsers" and wanted to pass on my reply to Mark's email. Since my query is related to the topic of glyph selection, I wanted to know if anyone in this mail group can tell me if doing a text can based on block ranges is more appropriate then the scan based on script ranges. It appears as I mentioned in email to Mark that Unicode fonts use block ranges. Can someone verify this?
chuck ----------------------------------------------------- Thanks. My goal is to determine if a unicode font can print all the characters in a text file. I'm unsure if I should check characters based on range as specified in Blocks-3.2.0.txt or check characters based on script as specified in Scripts-3.2.0.txt. If I check the properties of a unicode font such as times.ttf it returns the supported unicode ranges such as 'Basic Latin', 'Latin 1 Supplement', 'Latin Extended A', 'Greek', 'Cyrillic', etc. Based on this it appears that unicode fonts support the ranges as specified in blocks.txt. If this is true, it is a much easier task to scan the text to find out what ranges are covered and see if that matches the fonts supported ranges. Would you say that if my goal is to verify all UTF-16 text can be printed then I should do range checks rather then script checks?
