Cannot add a layer datasource that has an apostrophe in the file name

[piratepoodle]

Dear TileMill Community,

Please help fix the following issue:

When trying to add a layer datasource that has an apostrophe in the file name the datasource cannot be added.

Workaround:

Check the full datasource path and rename the file without an apostrophe.

Error:

  File not found at absolute path:
  'C:\Users\%USERPROFILE%\Documents\%PROJECTNAME%\Public Transport\Britain'

  TileMill Error

thanks for the report. I can replicate on OS X, but I don't see an easy/obvious way to fix. Please plan to stick with the workaround of re-naming the file.

Perhaps someone can write some code so TileMill can automatically detect a file name with an apostrophe and notify the user of an incompatible file name and prompt to rename the file? This way the exception is handled before a crash.
