summary: Unicode strings in Windows GUI configuration accidentally limited to 127 characters
class: bug: This is clearly an actual problem we want fixed.
present-in: 0.82
fixed-in: e7acb9f6968d48217a4210dd91b742e82f80bc72 ce7a451d6e307dd5442fefaf8b0a17bcc7fca5f8 (0.83)

When you enter a string into an edit box in PuTTY's GUI configuration, if PuTTY interprets the string as Unicode, then it is accidentally truncated at 127 characters.

As of PuTTY 0.82, we're in the process of gradually transitioning PuTTY's configuration in the direction of better Unicode support. So this doesn't affect all strings in the configuration. But it does affect filenames, in particular. So if you configure (for example) a pathname of a private key file to load, or a pathname of a log file to write, and that pathname is longer than 127 characters, PuTTY 0.82 will truncate the pathname to 127 characters and try to use the short version.
