I encountered two issues, one minor and one more significant.
I define a custom CRS using these parameters. Give it a name "Everest_India_Nepal_custom". Save the CRS. Use it when georectifying a toposheet. Save the toposheet with this new CRS. (gtif file). But when I reopen that gtif file in a new project, its properties show the CRS parameters, but do not show the custom name I had given for ease of recognition. When saving it said :User 100001: Everest... But when opeining it says "User 100009: *Generated CRS....". So it does not remember the name I gave. Although the name still shows up in CRS options.
bigger problem: if I try to validate this custom CRS by using the "calculate" button at the bottom of the custom CRS window, i get rubbish. But the CRS definition is correct, and it works--when my rectified topo is placed on google earth, it sits perfectly (error <10m).

For the first issue, add a +wktext at the end of your proj string. This will preserve your custom CRS including the name.
Otherwise QGIS tries to find a suitable CRS in the EPSG database from the WKT definition in the file, and create a new custom CRS if nothing matches.
For the second one, I can not help you much. I don't use that calculator.

伟大的！我有一段时间了这个问题。使用+ wktext做了诀窍。我在哪里可以找到有关此参数的信息？我在proj.4参数列表中搜索，并没有找到任何 Ernesto561 2017-08-27 20:15:05Z, License: CC BY-SA 3.0
只有一件事，它在所有情况下都不工作。我使用GDAL光栅化工具来栅格化一些行，结果的CRS是生成的CRS。线条层和项目的CRS是相同的自定义CRS。 Ernesto561 2017-08-28 04:06:37Z, License: CC BY-SA 3.0

Great! I have had this problem for some time. Using +wktext did the trick. Where can I find information about this parameter? I searched in the proj.4 parameters list and didn`t find anyting Ernesto561 2017-08-27 20:15:05Z, License: CC BY-SA 3.0
Just one thing, it doesn't work in all cases. I am rasterizing some lines using the GDAL Rasterize tool and the CRS of the result is a generated CRS. The CRS for the lines layer and the project is the same custom CRS Ernesto561 2017-08-28 04:06:37Z, License: CC BY-SA 3.0
