Subject [jira] [Created] (SIS-205) Enforce character encoding restriction
Date Thu, 02 Jul 2015 17:28:04 GMT
Martin Desruisseaux created SIS-205:
---------------------------------------

             Summary: Enforce character encoding restriction
                 Key: SIS-205
                 URL: https://issues.apache.org/jira/browse/SIS-205
             Project: Spatial Information Systems
          Issue Type: Sub-task
          Components: Referencing
    Affects Versions: 0.5, 0.4
            Reporter: Martin Desruisseaux
            Assignee: Martin Desruisseaux
            Priority: Minor
             Fix For: 0.6


ISO 19162 requires that we restrict to the following characters in all quoted texts except
in {{REMARKS}} elements:

{noformat}
A-Z a-z 0-9 _ [ ] ( ) { } < = > . , : ; + - (space) % & ' " * ^ / \ ? | °
{noformat}

They are ASCII codes 32 to 125 inclusive except ! (33), # (35), $ (36), @ (64) and ` (96),
plus the addition of ° (176). In particular, the specification recommends:

* to use (_P_, _L_) as the transliteration of the Greek letters (_phi_, _lambda_) in axis
abbreviations, or alternatively (_B_, _L_) or (_lat_, _long_),
* to use (_U_) as a replacement for (_theta_) in polar coordinate system,
* to use (_U_,_V_) as replacements for (_phi_, _theta_) in spherical coordinate system.

-Those restrictions are currently not enforced in SIS.-
{color:red}Update (May 2015):{color} newly added {{CharEncoding}} class now handle some (not
all) of those cases.
