Hello, With Pharo3, in an object of mine, I want its text representation to come with the EURO symbol: CGMoney>>printOn: aStream aStream << (amount asScaledDecimal: 2) greaseString << ' ' << 'â¬' It appears to be very slow when I browse such collection of objects (says 1500) from an inspector Replacing 'â¬' by 'EUR' gives back normal rendering time. Indeed the 'â¬' is encoded as WideString, so not sure what is happening. All content converted to WideString or what? The issue was discussed in the Seaside mailing list and different suggestions raised as well benchmarks exposing the issue: http://forum.world.st/TableReport-slow-down-tp4868925.html I tested these benchs en Pharo 3 and 4 and the performance diagnostics are the same. There are matching reports to some extent: https://pharo.fogbugz.com/f/cases/6639/Buffered-Text-Converters https://pharo.fogbugz.com/f/cases/14279/EyeInspector-very-slow-on-WideString https://pharo.fogbugz.com/f/cases/10868/Slow-UTF8-decoding Nevertheless, the problem of the performance remains.
