Combining characters bug[edit]
In the past Verdana (v. 2.43) had an incorrect position for combining diacritical marks, causing them to display on the following character instead of the preceding. This made it unsuitable for Unicode-encoded text such as Cyrillic or Greek. This bug didn't usually reveal itself with Latin letters. This is because some font display engines substitute sequences of base character + combining character with a precomposed character glyph.[14] This bug was subsequently fixed in the version issued with Windows Vista. It is also fixed in Verdana version 5.01 font on Windows XP by installing the European Union Expansion Font Update from Microsoft.[15]
