Even dash can have compatibility issues if someone produces a hyphen because they think hyphen and dash are the same.
But, yet again, any character except colon is valid on Mac ( Audacity Manual )
so should not prevent Audacity exporting unless there is an Audacity bug. This assumes you are using the latest Audacity version from Audacity ® | Download for Mac OS .
The known bugs in current Audacity that cause exports to fail when they shouldn’t:
- (OS X and Linux) Entering a backslash “” in a file name when saving a project gives a “Could not save project. Path not found.” error.
- (OS X and Linux) When using Export Multiple, asterisks (*) or question marks (?) in labels are wrongly rejected as illegal characters, and forward slashes (/) cause a false “cannot export audio” warning. Workaround: To force use of * or ? (and / on OS X), export each region with File > Export Selection instead (/ is illegal in a file or folder name on Linux).
