Hi, I'm having difficulties with Unicode characters with R 2.7.0 on Windows XP SP2. I'd like to use a delta character, which I'd also like to mix with other formatted output using paste() or sprintf(). On my system, I can successfully do this with a static string: print("\u0394Q = 2.2 L/s") [1] "?Q = 2.2 L/s" However, when I use paste() or sprintf(), the Unicodeness is lost: paste("\u0394Q =",round(1.2345,3),"L/s") [1] "<U+0394>Q = 1.234 L/s" sprintf("\u0394Q = %.3f L/s",1.2345) [1] "<U+0394>Q = 1.234 L/s" Any incite why this happens? Also are there any suggestions or workarounds that I can use to produce a formatted string rather than a static string? Thanks in advance. +mt
