Histogram title inserts blank space before special character

ROOT
1

any suggestions on how to avoid this problem? it seems strictly related to the length of the title.

void test(){
  TH2F* tempTH2F1 = new TH2F("testName1", "testTitle1", 32, 0.5, 32.5, 68, 0.5, 68.5);
  TH2F* tempTH2F2 = new TH2F("testName2", "testTitle2", 32, 0.5, 32.5, 68, 0.5, 68.5);
  string histName1 = tempTH2F1->GetName();
  string histName2 = tempTH2F2->GetName();
  tempTH2F1->SetTitle("Simulated (50ns BC) Pixel Hit Rate (Hits/cm^{2}/s) per ROC for Disk -1");
  tempTH2F2->SetTitle("Simulated (50ns BC) Pixel Hit Rate (Hits/cm^{2}/s) per ROC for Disk -10");
  TCanvas* tempCanvas1 = new TCanvas(histName1.c_str());
  TCanvas* tempCanvas2 = new TCanvas(histName2.c_str());
  tempCanvas1->cd();
  tempTH2F1->Draw();
  tempCanvas1->Print((histName1 + ".png").c_str());
  tempCanvas2->cd();
  tempTH2F2->Draw();
  tempCanvas2->Print((histName2 + ".png").c_str());
  delete tempTH2F1;
  delete tempTH2F2;
}

The simple following macro is enough:

{
TLatex l(.1,.5,"Simulated (50ns BC) Pixel Hit Rate (Hits/cm^{2}/s) per ROC for Disk -1");
l.Draw();
}

It is funny because it shows only with the png outpout

still investigating

Now fixed in the trunk and in 5.34
Thanks for reporting.
